So I am newly pregnant with my 2nd little one about 5 wks 3 days. I currently have a 14 month old son who is about 30 lbs. my SO is convinced I shouldn’t pick him up. However I keep telling him it’s not like it’s something new for my body. Anyone have any advice or know from experience what the dr would say? My first apt isn’t till next week so turning to you all. I feel like going from 1-2 switches some rules around
