When and how do I tell my toddler he’s going to be a big brother?

Marisa

My son is 2 1/2. I’m only 8 weeks pregnant and I’ve had a bit of a scare so I know I want to wait a little bit. I don’t know if he’ll understand. Is there a good way to explain it to someone that young? And is there any way to prepare him mentally to an extent? He’s used to being my entire world and I know it will be a huge adjustment. Any advice is appreciated.
