I also have worked in a childcare centre and now a sahm and i agree that it is hard for some children to get used to one day a week and i would suggest two days a week even just to start with till she gets used to it. And it also does NOT mean you are lazy, at the end of the day she will probably LOVE it and so will you. Its a good idea to start it sooner then later so she is settled before the new bubs arrives. Hope this helps

Good Luck
