Hi everyone, We are new to CDing and just second day using our FBs. I love the way they feel and how I haven't had any blow-outs of leaks yet. BUT I notice that my DS's legs and his waist (back) have pretty awful looking red marks after removing the diapers Right now he is 18.5 lbs and 24'' (Pretty chubby for a 3 1/2 month old I know). I have the waist elastic setting on his back to the last one so 1 and the legs on 3. If I go to 2 I see air and they are loose so I am afraid of leaking.... What to do?
