Dilemma - DS is very in between sizes right now. 12-18 pants are too short (but fit in waist). 18-24 pants are big in the waist and long. 12-18 shirts fit, 18-24 are huge. If I put him in these clothes he looks funny but it would be stupid to buy fall clothes in 12-18 months right? Just stick with the bigger sizes. The kid has gained 5 pounds since he was 6 months old - he's just gotten taller and is constantly on the go but an awesome eater. I can't complain just no idea how to buy clothes for him now. Help me not waste my money.
