Thanks, all.
I'll try the brand name onesies. I didn't pay attention to the brand I was looking at
If not, I guess I'll just have to hand-sew it to fit. Oh well
I don't know if she'll try and get at them...but I do want something there to kind of help protect against any extra dirt getting in. So, I definitely want it loose so the bacteria doesn't get pushed in.
I've got a couple weeks to figure everything out - thank God!
