Hi C., I am a day care provider, and I have had babies in mycare as young as 6 weeks old,kids not socializing until they are 20 months old is not true. The babies that I have had in my care, as soon as they can sit up or crawl they are socializing with the older kids. I will be honest with you, the vest place for baby is at home with mommy, no matter how good the daycare or nanny, it does not take the place of mommy, also banies bond with the one they are with the most, babies in my care don't want to leave when they are picked up, because I'm the one that is nuturing them all day. I was a SAHM for all 3 of my kids, and I didn't miss a thing, as a provider, I saw the babies roll ove for the first time, crawl for the first time, take their first step, hear their first word, that's what you miss C. when you put your babies in someone elses care. I would not use a nanny. In choosing a daycare, make sure that they have open door policy, if not do not choose that daycare, also choose one who believes in tummy time, and can provide different activities for your son. Hope this helped, mom for 24 years Day care provider for 11. J.
