Charades Unisex Baby Little Bee Costume

It doesn’t let me chose a size only says toddler does it fit a 12 month old

My son is 14 months old, about 25 lbs. What size should I get?

For a 23lb 11 month old (usually size 18-24 months) should I get an infant or toddler?

Will this fit a 38" boy who weighs 36 lbs?
