Ok, so, with my 2 year old I spent SO MUCH MONEY CDing. I turned semi-hyena and didn't like what that did to my bank account. I'm thinking with baby #2 we'll completely simplify and only use flats and bummis. So, are there any of you that only uses flats? About how many do you need for a newborn? I'm not even pregnant yet,i just like being prepared. Also, can toddlers use flats? I have 2-3 that I used on my son when he was itty bitty but I tried putting one on him now (he's 2 years old and 30 lbs) it was impossible. Maybe i'm doing something wrong?
