working in childcare while pregnant

Danielle • I have a 6 year old son and am pregnant with baby number 3! I had a miscarriage and am now 36 weeks!
I am 22 weeks pregnant and work at a daycare in the one year old room up to twos, I have to lift them up on the changing table multiple times a day. It doesn't feel like it's straining my body or anything but I know a couple of them weight at least 35 pounds. Is it bad for me? Or will I be fine?
