Hello! Calm down. As long as your son knows he is important to you and you spend time together, he will be fine. Make sure you remember to take the time out when you can and to listen to him. All kids really wantis be loved. I am sure you love him and he knows that. As for a sechedule, I would say breakfast around 8:00-8:30. Play time while learnign after that, outside time, lunch around 11:30-12:00. Nap after that. It is usually best to have him up by 2:30 or 3:00 so he can go to bed at a good hour. After nap, have a snack, then more play outside time. Dinner around 6:00, bath, book bed. Kids learn through plaing. While you are playing make sure you are talking to him abuot what he is doing and colors, shapes, etc. That is how they learn.
I work in child care and am currently in school for early childhood education. I want to open a pre-school. As long as you are remembering to take the time out, and listing to him, you will be fine. When the baby comes, rememeber to keep taking the time out and listing to him. It will be a lot harder but it will help him. Also, let him help with the baby. Let him help feed, change, bath the baby. he can help gather the materials for the event and so forth. It will bring all of you closer.
