Hi, again, E.!
Well...since you have a choice, that's good. When my son was about that age, I had to go back to work, so I had to get him into daycare whether he was ready or not. I'm very glad that you are able to make the choice, rather than to be forced into it. That is a reason to celebrate.
I think there are some factors you can use to decide whether or not your boy is ready for the daycare/preschool experience. First of all, are there similar experiences avaiable to him already, such as playgroups, pre-K Sunday school or nursery, or children's church, where he is with a teacher and a bunch of other kids, but away from you? If so, how does he respond? Does he like the experience, or does he have trouble with it? And in general, does he have a lot of separation anxiety when you leave him with someone else?
If he seems to enjoy or at least adjust well to these kinds of situations, then he may be ready for pre-K. Bear in mind that boys quite often are not ready as early as girls are for socializing without Mom being in the room. It's not a hard and fast rule, but in general, boys need a little more time to mature than girls do when it comes to pre-K.
On the other hand, if he seems to have a lot of anxiety or is otherwise uncomfortable in social situations when you have to leave, it might be wise to wait, spend more mother-son time, and possibly introduce him to similar experiences gradually so that he can adjust gradually to pre-K. Then, if your situation changes and you HAVE to get him into daycare in order to work, it won't be so traumatic (for both of you!).
BTW, you and I are almost neighbors! I live in North Miami Beach, just a few miles south of Aventura ( : Howdy, neighbor!
I hope this is helpful. Personally, if I didn't HAVE to send a very young kid to school, I would keep him or her close to me for as long as possible. Everything he might learn at pre-K can be taught at home, in museums, in parks, in the supermarket, at the playground, at church, etc. But follow your heart, and not what society might be pressuring you to do. I think as long as you do not isolate the two of you, and you keep on giving him socially stimulating and mind-stimulating, fun experiences, you can't go wrong by giving him your time and happy nurturing.
Peace,
Syl
