Cant keep his pants on

What do you mommas do when your kiddos are in between sizes? My 21 month old just started outgrowing his 18 month clothes, mostly his pants, his onesies still fit him pretty well. His pants wont go up over his butt and if I manage to get them on they start to fall off.

I bought him 24 month clothes but they're all so big on him, hes swimming in them. His pants are constantly falling down and I have to roll all of his pant legs because hes on the shorter side.

What did you ladies do to keep your toddlers pants to stay on? Especially while in between sizes.
