Hi! im a mom to a 2 year old and a 3 month old too! (however im a stay at home mom) BUT... I worked in day care and as a nanny for 13 years!
so , i can say it is normal for your son to cry when you drop him off, especially if hes never been in a day care setting before. some kids it takes a few dys to adjust others weeks, some always cry when dropped off(i had one boy do this for 2 yrs!but once his mom was gone he be fine and didnt want to go home when she came back to pick hime up.)how is your son when you pick him up?
at the day care i worked parents could come & go as they pleased. so we had parents who would stay and watch where there kid couldnt see them, or come back in alittle while just to check to see if they stop crying and i had parents who called on a daily basis to check on there child. so you do what makes you comfortable. i will say it is easier on the child to do a quick drop off and hugs &byes for a child who is having a hard time. then just check on him in a little while.
feel free to ask me any questions about day care! C.(momo of ashley 2(a week ago) and jackson 3 months)
