It hard that's for sure. I cried every day for 2 weeks when my maternity leave was up and I knew I had to go back to work. I couldn't bear the thought of leaving my baby, but there is no way we could survive on one income, so I had no real choice.
I cried the morning I dropped him off and called to check in way too many times. It got easier every day, though it still sucks. I know for me I have a lot of trust in my daycare, which is Jaylon's grandmother and that helps tremendously.
It's good for babies to be around other kids, and if you like your sitter and have confidence in their skills that makes it feel better.
