My son started daycare at age 18 months (previously he was watched by my neighbor who watched him from 6 weeks on). He is 22 months old now. The first month was hard. In fact, it was odd cause the first day I dropped him off, he didn't cry at all (home based daycare) but he refused to eat the entire day. The second day the crying started during drop off. I called about 10 min after I dropped him off and he was fine. The crying would stop in under three minutes. As time went on, each day he would still cry, but the durations was shorter and shorter. What I thought was odd, was for the first two weeks or so when I would pick him up he would cry when he saw me, as if it was some emotional outlet. I was told this is normal. Sometimes he would cry when i said I had to go, yet would stop before I even made it out the door. I guess it was his attempt to get me to stay or something. I would just hug and kiss him and say Mommy had to go and leave, cause I do believe the longer you stay, the worse (cause I did that the first week). Four months into this, sometimes he gives me the pout lip but that's it. I think they would just prefer to have fun with mommy sometimes. Good luck.
