Does anyone know the waist measurement for size 3-4? I bought 5-6 for my slim 7 year old and it was way too big.

There may be sizing on the information page? I'm not too sure, but if bot maybe try googling average waist sizes and measure up your child to see which ones to get? Hope this helps.

My son is super slim to do growth issues. He needs 5-6 length but trunks always fall down. Are these good for slim kids?

I bought these for my grandson who is very slim, he's 11 but i bought him age 9-10 and they were perfect for him.

Do they have side slits ?

No, the do have pockets though. Really decent lightweight swim short overall.
