E.Y.
I started my daughter at daycare when she was 4 months old, and she was probably 7-8 months old before I started to feel really good about my choice. They only reason I didn't pull her out was because all of the older babies looked so happy there. Now that she is 13 mos old, she couldn't be happier there! She loves the stimulation. But, the first few months were really rough for her and for me. She refused to take bottles there (only drinking 0.5 - 2 ounces/day there), refused to nap, and would make up her missed ounces by nursing all night long for the first couple months. Her caregivers were extremely loving, but it just took my daughter an unusually long time to adjust. (She is just a child who is EXTREMELY resistant to change, but I am guessing that this issue would be even worse if I kept her at home with a nanny.) My husband and I already talked about how sad we will be when she has to transition to the toddler room because she just loves her infant room now! I would suggest waiting until he is not sick or teething for a few weeks, plus spend some time looking at the other babies (are they happy? engaged? thriving? at or above average in meeting milestones?) before making any decisions. In the meantime, I can relate to how tough the transition can be! Good luck!
