If your husband is going to be there with you then you shouldn't have an issue because even if you are up through the night with the baby you can get a nap during the day. I am mom to four. i started daycare when my second child was 4 months old so two of mine were born while I did care. For both I had a week off and parents knew that for the next month or even 2 the basic needs of the daycare would be met but programming would be mostly halted and it would be freeplay. They were more concerned that the children maintain continuity that what they learned academically for that period. "Back in those days", there was no such thing as paternity leave so I did it on my own and the key for me was having my hubby let me take a nap after dinner while he watched the kids. I had to be careful not to sit for too long or I was likely to dose off and that was my primary concern. I used the playpen more for the youngest I had in care just in case.

In your case what you might want to do is suggest the school age kids go to summer camps or a dayprogram for this summer as you won't be wanting to do much with them and it would means a quieter afternoon as little ones would nap.
