I’ve bought the smaller baby size in the past, decided to buy 74/80, 86/92, and 98/104 for big kids and they are just as amazing! The 74/80 fits my 1.5 year old with plenty of room, the 86/92 will fit my almost 4 year old this season but with barely any room to grow. The 98/104 fits my 5 1/2 year old with plenty of room! They are nice and cozy, good quality and not too thick! I used to like sloomb pants but got tired of all of the snags and runs, these hold up much nicer and I don’t worry about them just being kids! Highly recommend!
