WHAT SIZE SHOE DOES YOUR KID WEAR AND HOW OLD ARE THEY?! EDIT

I've posted this is another area but not getting any responses....

I've come to realize that both my kids are gonna have big feet. Brayden(son)is in 10.5/11 in YOUTH at 3.5 years old he's the height of a 5 year old and haley(daughter)is in size 5w in TODDLER she's only 14 months and tall as well!!!

For those that wanna comment on his carseat it is not his normal car seat I had to use it because the other was in my other car but the one he is in he fits all the recommendations except the age which I was told doesn't really matter as long as he's not like 2 years old. He will be 4 soon; I took it to my local fire department via recommendation by the police department and they said he was fine. I shouldn't have to explain myself I know what I am doing this isn't my first time so please this post isn't about my son's carseat it's about shoes so let's stick to what the post is a out!!
