Re: CDing just great, until winter
I live in Phoenix, so I don't know if these would be warm enough.
Wal Mart sells thin knit pants (kid connection) in assorted colors that match the T-shirts. They are loose enough to fit over a cloth diaper, and cost under $4.00 a pair. You can't miss them, they take up half the baby section.
If he's a real chunky baby, you can buy a toddler size, and cut the bottom of the legs off. That would be very easy to hem. You could even put elstic in the cuff when you hem it, so they don't ride up to his knees.
Anyway, I love those pants, they are my favorite.
