Anyone else have a hard time lifting or holding their toddler?

My 2.5 year old weighs about 30 lbs and although he walks, I still have to hold or lift him sometimes like when we go out for a few hours (he can’t walk for too long and won’t sit in the stroller) or when I change his diaper, give him a shower, take him in and out of the car seat, etc. and it’s becoming harder and harder with the little one in my belly... anyone else feel the same way? How do you cope?
