For sure, he still has a lot of growing to do IY"H. This would be in favor of sticking with 1 hat for now I suppose.
Yes.
My BM hat, had a foam pad put in because it was too big. (Store didn't have any smaller.)
1.5 years later, pad came out.
3 years later, hat didn't fit on my head.
(Something like that, it's been a while.
)
Point being, if not for the foam pad, hat would've only lasted for around 2 years or less...
