My son is pretty long he was 21 inches when he was born, and is now about 22 1/2 inches long.. He doesn't fit in 0-3 month clothes unless it's stretchy but 3-6 months fit him so loosely lol.. My poor guy ☹️
I know how you feel, my son was 21 inches when born and only weighed 6lbs, and at 4 months old he was 27.1 inches. no clothes are long enough unless they're big on him everywhere else.
