Could be his position right now. I know I've had periods of time that I was bigger then other times.
Jr is a kick boxer too. He also gets hiccups all the time
Agreed!! My bump pics with chloe looked tiny all the way up through and when she finally flipped, my stomach literally popped overnight, lol! Position is definitely key and at 26w you're not even at the "Home stretch" where they get biggest.. as long as baby is kicking good and measuring good I wouldn't be worried at all!
