My boys are both long, which makes finding fitting pants/overalls a little on the difficult side, but these overalls fit both my 4 year old (who is in a 5/6) and my 12 month old (18mon) great! The fabric is also super soft and the Bumble Nums are a family favorite for us. I absolutely recommend them!!
The tee sits so it gives a slimming fit across the abdomen. I'm only sorry it doesn't come in more colors.
The material is so soft and stretchy! My baby loves his pajamas. I ordered the 6-12 month. My baby is 6 months and 15 #
