Toddler and baby - please help !! 😀

I dont usually post but Id like to ask if anyone has any advice for me. My son is 19.5 months old and Im due in January but Im not exactly sure how to teach him about the baby...

I have been trying to tell him that there is a baby my belly so he cant like jump all over me since I first found out but he doesnt really seem to understand and we tell him hes going to have a brother soon.

Both of my sisters recently had babies this year and Ive tried showing him the baby and he just doesnt really care so Im kind of scared about how he will react after the baby is born. We are starting to get our newborn stuff out and we are getting all the other stuff next month.

Anyway does anyone know a good way that I can try to teach my son about the baby.

Ive also tried getting him to feel the baby move but he doesnt like when I hold his hand down on my belly.
