Anyone Else Worried About Picking Up Their Older Child While Pregnant?

Chelsea • Wife 💍 to hubs of 10 years & mommy to our 3 y.o. boy 👦, pregnant with baby # 2

So I’m in my first trimester. My son is 3 and 37 pounds! My son has Autism, and he goes to applied behavioral analysis 40 hours a week because he has moderate to severe Autism—please don’t get me started on the symptoms of Autism but this is relevant to my question I promise. At ABA they teach him how to communicate what he wants by using positive reinforcement. My son can now say “up” when he wants picked up. For him to do that, it is HUGE and for him to continue to do it, we are supposed to honor his request which is the positive reinforcement for us to pick him up. He loves to be held and cuddled. I haven’t had any issues with holding him and carrying him while pregnant, but I’m nervous he’s too heavy to carry. DH is amazing and tries to do most of the picking up/carrying our son. Should I keep picking him up or should I ask his therapists for a solution on how to honor his request or get our son to understand that mommy can’t pick him up all the time?
