Should I put my 9-12 month old in sleepers during the summer?

Okay, obviously not outside, but inside? I always have the AC on! I personally burn hot so I have it up fairy high while I wear a sweater because it’s comfy (don’t judge😂)

So I’m wondering if I should buy my son sleepers for around the house and for bedtime? He still sleeps in a sleep sack as welll. Or should I put him in a long sleep onesie with the sleep sack during the summer months? If so, should I even bother with sleepers? Or should I just have a few on hand JUST IN CASE?

Sorry First time mama here!
