I can't think of any way to make snaps 'snap' any tighter, I think I'd simply replace the snaps - unless that's more trouble than it's worth.

Are these the snaps that run up & down the inside leg seams of toddler clothes?You didn't say, but I'm assuming that's what you meant - if so, you can look for snap tape @ the fabric stores - shouldn't be too much trouble to replace that.

Yes, they are the snaps between the legs. I thinking ripping them out and resetting them would be more trouble than it's worth. Unless I sewed in snap tape, the snaps would probably rip out (maybe?) because there had already been a snap there before. I thought about sewing velcro in between each snap but I don't know if that would be worth it either. Good money down the drain! And these are Osh Kosh too. Maybe I should contact the company.

As a last resort you might try this; lightly tap the ball portion of the snap with a hammer. It will slightly flatten and widen the little ball portion and make it stay in the socket.

I used Eunice's lil' trick many times when I had toddlers...it works. (If you don't smash 'em like I did the first one.)

Hey Eunice, I will try it! That sounds like a great idea. There's so much room still but David is so active and climbing onto everything, before I know it his 'mudflaps' are wide open. LOL Thanks for the tip!
