KATIE與慧嫻來出席婚宴，兩人都以為芷青的大喜之日，怎知道來到酒店的時候才發(fā)現(xiàn)原來是芷青的爸結(jié)婚。兩人看到芷的老媽也出席，還幫招待客人，覺得匪夷思，更吃驚的是看到青的老爸娶了一個比兒來得年輕的嫩草。年KATIE，慧嫻和芷青是在拉薩學(xué)院就服裝設(shè)計。畢業(yè)后，人各奔前程，往不同行業(yè)發(fā)展。KATIE學(xué)以致用，當(dāng)上了名計師，芷青卻誤打誤進(jìn)入了電視臺當(dāng)副導(dǎo)，挨了幾年后，終于大梁當(dāng)上導(dǎo)演，最不志的就是慧嫻，她目是在一家女性雜志社任記者，主要采訪服時尚服飾，對慧嫻來，她最大的成就就是給當(dāng)導(dǎo)演，疼愛她的老公傅煒銘。KATIE嫁給了當(dāng)廣告平面設(shè)計師的JOVAN，育有一個九個月大，可的女寶寶。一天，KATIE翻看I周刊雜志，發(fā)現(xiàn)影視制作公司籌備開拍《奶爸百分2》，找尋女寶寶出演電視劇。KATIE不顧JOVAN反對帶寶寶去試鏡，寶寶在鏡前呆呆的沒反應(yīng)，KATIE還以為試鏡失敗大表失望，沒料到女制不顧導(dǎo)演反對，堅錄取宣宣。KATIE知道后，欣喜若狂把寶舉起來，卻搞得寶整個人跌落在地上，得他們要命！為了要寶寶去拍戲，KATIE要JOVAN拿兩個月的無薪假，JOVAN的公司不肯放人，JOVAN被逼辭職，當(dāng)起了全職奶爸。戲開時，寶寶變幻莫測的緒，搞到片場天翻地，每個人都出盡法寶哄寶寶，兩個導(dǎo)演也寶寶搞得精疲力竭。了要讓寶寶與戲里的主角仁賢培養(yǎng)感情，演要求仁賢住進(jìn)KATIE家。KATIE與JOVAN除了要照顧小寶寶外，還要照顧來張口，衣來伸手的BABY，讓兩人忙上加忙?；蹕姑刻於悸?煒銘的抱怨，忍不住他會不會因此而對寶產(chǎn)生恐懼感？這一對妻結(jié)婚多年一直沒有孕，煒銘很渴望有自的孩子，慧嫻卻對懷有恐懼感，不敢坦白公，只能默默的配合慧嫻的家婆也一直尋受孕的土方，搞到小口啼笑皆非。自從煒的弟弟煒德娶了一個有兩名兒子的離婚婦來后，慧嫻隱隱感到家中的地位受到威脅更感壓力。自從JOVAN辭職后，心情顯得郁郁寡歡，KATIE因為過于關(guān)注工作和寶，忽略了JOVAN，兩人的關(guān)系日漸惡，JOVAN在外頭尋找宣泄的管道，卻不心遭人陷害，他被一女人控訴性侵犯，還此被抓去警局接受調(diào)。追求完美的KATIE，無法接受老公這個污點，任憑JOVAN怎么解釋，她都不相。JOVAN因此性情大變，把自己封閉在里，宣宣無法去拍戲搞到劇組陣腳大亂。時，KATIE的公司要委派她出外公干，KATIE想乘機離開新加坡散心，卻放不下宣，芷青為了要讓宣繼續(xù)拍戲，只好自告勇當(dāng)起宣宣的奶媽，而，沒幾天她就投降，還找來仁賢助她一之力，在這個過程里抱著獨身主義的芷青覺到仁賢對她有意思心里很恐慌，故意逃仁賢，也只好把這個手的山芋丟給了很有心的煒銘。宣宣就這被兩個導(dǎo)演當(dāng)著人球樣的拋來又拋去，煒開始了他短暫的奶爸涯，慧嫻當(dāng)然也在這過程中，漸漸的喜歡孩子。。。沒多久，嫻傳來喜訊，JOVAN終于洗脫了嫌疑，他和KATIE和好如初，KATIE還懷上了第二胎，為了兼顧家與事業(yè)，一向排斥與婆家翁同住的她，終明白家有一老，如有寶的真諦，把兩個老接來同住。與此同時芷青也傳來了婚訊。。KATIE and HUIXIAN went to attend a wedding dinner, thinking that it was ZHIQINGs big day. However, to their surprise, it turned out to be ZHIQINGs fathers wedding. Both of them were equally amazed to see ZHIQINGs mother helping to entertain the guests. The most surprising moment of the day was when both of them saw the bride, who turned out to be younger than ZHIQING!KATIE, HUIXIAN and ZHIQING studied Fashion Design together at Lasalle College of Arts. After graduating, the 3 ladies went pursued different careers. KATIE practiced what she studied and became a fashion designer. Unexpectedly, ZHIQING became an assistant director at a production house and after several years, became a director. The least ambitious, HUIXIAN, was working as reporter of a female fashion magazine, covering the latest fashion-wear and accessories. To HUIXIAN, her biggest achievement was to have married her doting husband, BO WEI MING, a director.KATIE was married to advertising graphics designer, JOVAN, and had a 9-month old adorable baby girl. KATIE was flipping through i-Weekly one day when she saw an advertisement stating that a production house was going to produce a new TV serial, "Nanny Daddy 2", and was looking for a baby girl. KATIE, ignoring JOVANs protests, brought her baby to the audition. During the audition, XUAN-XUAN could only stare blankly at the camera. KATIE was almost sure that they had failed the audition. Despite the directors protests, the executive producer persisted in using XUAN-XUAN. Ecstatic, KATIE happily heaved her baby, but accidentally caused XUAN-XUAN to fall, shocking those around her. To enable the baby to act in the serial, KATIE asked JOVAN to take two months unpaid leave. Unfortunately, JOVANs company did not want to approve his leave and he was, in turn, forced to quit, becoming a full-time stay-at-home dad.XUAN-XUAN became cranky and unpredictable during filming, creating chaos on the set. Everyone in the studio tried all ways to cheer XUAN-XUAN up, and the two directors were drained out in the process. The director requested for the male lead, RENXIAN, to move in temporarily with XUAN-XUAN to foster a bond between the two. Unfortunately for KATIE and JOVAN, RENXIAN didnt know how to care for himself and was incredibly dependent.HUIXIAN, after listening to WEIMINGs incessant complaints, curiously asked if he developed a phobia of babies. This couple had no children after many years of marriage. WEIMING yearned for his own child. HUIXIAN, on the other hand, had a morbid fear of pregnancy. As she did not dare tell her husband about it, she could only silently comply with his wishes. HUIXIANs mother-in-law kept searching for ways to get her pregnant, which created much awkwardness. Ever since WEIMINGs younger brother, WEIDE, married a widow with two sons in tow, HUIXIAN felt her status in the house affected and she became more stressed out.Since JOVAN quit his job, he started to slip into depression. KATIE was excessively preoccupied with her work and XUAN-XUAN, completely neglecting JOVAN. This strained their relationship further. JOVAN started to seek solace out of his home and was entrapped in a molest case. Accused of molestation, JOVAN was arrested by the police for further investigation. A perfectionist, KATIE could not accept this incident. No matter how JOVAN explained, she was unconvinced. Henceforth, JOVAN became a changed man, as he locked himself at home. XUAN-XUAN was thus unable to attend filming sessions, which caused problems to the production team. Meanwhile, KATIEs company wanted to send her on a business trip overseas. KATIE wanted to take this opportunity to get away from it all, but was worried about XUAN-XUAN. ZHIQING volunteered to care for XUAN-XUAN while KATIEs abroad so that filming would not be disrupted. A few days into the "job", ZHIQING gave up and got RENXIAN to give her a hand. ZHIQING, who was bent on remaining single for life, felt RENXIANs affections for her and panicked. She started to avoid RENXIAN and had no choice but to pass XUAN-XUAN to the compassionate WEIMING. Hence, XUAN-XUAN was being passed like a ball between the two directors. WEIMING experienced what it was like being a father and HUIXIAN began to like children. Not long later, HUIXIAN found herself pregnant.JOVANs name was cleared, and he and KATIE were back together. KATIE became pregnant again. To balance between family and work, KATIE decided to let invite her in-laws to stay with them (though she was originally averse to the idea of living with them), as she finally understood how valuable it was to have the elderly around in the house. At this point, ZHIQING also had good news to share.
