Psychologists have done a ton of research on children being sent to daycare FT, PT, or with stay at home moms. There is NO difference. The biggest difference was seen by moms that were upset by the separation. The babies felt that upset. Know that daycare can be a wonderful experience for your little one. Allow yourself to get used to the idea and don't try to fight it. The more you can allow yourself to relax, the more likely that your child will have a great time.
Do not listen to the negativity. People know about ONE child that was abused, but they neglect the MILLIONS of children who thrive in daycare. Allow yourself and your son to adjust to daycare for a few months. I things really don't feel right, then look into another daycare.
I wish you peace and happiness with your decision.
