Congratulations and as others have said you will be able to make it work if you are willing to make the changes necessary. I started daycare when my second one was 4 months old and my last two were born into the daycare. It never occurred to me to take time off when they were born since I was home anyways and the difference was I sat to breastfeed them and sat to give other babies a bottle. I think how much time off from daycare you plan to take will have the biggest effect on your daycare and your daycare parents. Many will not return once their child has spent 3 or more months with another caregiver and got settled in so you may need to close and restart. You may decide to keep only the really little ones that nap more or you may keep just older children that are more self sufficient or just take school age children for awhile so you have days to yourself with the baby.

I think for me I found that having the daycare children there made it easier for my own children as it gave them something to do all day while I was busy with the baby or just sitting with my feet up for awhile. One of the reasons many parents leave their older child in care while they are home - mommies trying to catch up on lost sleep and sterilize bottles are just not a lot of fun.
