Clothes sizes

This is why it's better to label clothes by length of child like overseas.

My daughter has always fit clothes according to the age for the most part. 

My son was very small, started in preemie sized clothing and didnt get to 0-3 months until he was three months. Now it depends on the make of the clothing hes between a 24 month and a 3t. Most makes of clothing are made for chunky babys and pants fall off, he only wears jeans during the day so i can tie them up with a shoelace and most of his pjs iv sewn extra elastics onto. Hes 2 and a half and weighs 22 lbs

I think the only reason for that is because the companies are going By the average size for certain ages/months. My 3 year old is just growing out of 24 month old clothes and 2-3t still fit a little baggy on her. She is slim and a bit short for her age. Too. 

My daughter is 17 months, but she only wears 12 month clothing & some 6-9 months if it runs small

This is why I wish we copied companies overseas and did it by length. Much easier.

I've noticed alot of clothes are now listing suggested weight on the tags too. My daughter will be 4 months on the second and she's in 6-9 months clothes already. Her thighs are just too chunky for anything smaller. :D

That's why I don't buy the ones that only say 3 or 6 months. I get the ones that says 3-6 months or 6-12 months, etc. My son is tiny, almost 3 but he still fits his 12 month clothes.
