I’m almost 14 weeks pregnant and I’ve been talking to my 3 year old about the baby for a few weeks now and now suddenly when ever I hold my niece he says “that’s not her mommy that’s my mommy” and now he’s been saying things like he wants a diaper when he’s been potty trained for 6 months now. ( he just turned 3 2 weeks ago) I’m feeling like this has something to do with the pregnancy and I don’t know what to do I’m worried he’s going to have a really though time when the baby comes. He very much a mamas boy we’ve always been super close. Anyone experience something similar? I need advice. How can I make this easier for him
