Just a tip for new parents or those still feeding formula. Go to the formula manufacturers web sites (enfamil, similac and bright beginnings) and sign up for their "formula club". Enfamil sent me two cans of formula and a $10 off coupon. Similac sent me a can of formula and a bunch of $5 off coupons. Bright beginnings sent a $7.50 off coupon.
The bright beginnings looks like a good formula at a good price. I can get it at the local Longs or Walgreens for $19 for a much bigger can than similac or enfamil, plus all the cans have a $2 off coupon. It appears to have the same ingredients as the others and the same or better nutritional profile for roughly 2/3 the price.
If you have a fussy or gassy baby or they spit up a lot, try the soy based formulas. We had Gabe on the milk based for a couple of days and he was a pretty Mad Baby. As soon as we flipped him over to soy he was a happy camper. We tried some milk based out on him again last week and we were back to Mad Baby for a couple of days and he was spewing the stuff with regularity. Some babies will improve more than others with the formula change, the soy is simply easier to digest and produces less gas than the milk based. Theres a real psychological barrier to it though...everybody wants the baby to have milk. About the only difference is replacing a milk based protein powder with a soy based one. Our pediatrician had no qualms about it except she thought that the soy has less calcium...when we looked at the labels it was the other way around.
Its also worthwhile to check www.fatwallet.com
for the occasional longs, walgreens and amazon diaper deals. I set a keyword alert on fatwallet for 'diaper'. About once every 4-6 weeks amazon clears out diapers for some reason. On the last round I picked up 3 boxes of 204 count size 1/2's for $28 each with a $30 gift card if you bought 3, bringing the price to $18 a box. My local Sams Club sells the same box for $29. The $18 is no tax and shipped free to your door. I think after 10 boxes the UPS guy has just about had it with me though...
