Father of 6 kids - currently 20, 18, 16, 14, 13, and 9 We did disposable diapers, but I'd certainly look at cloth diapers now. They've made a lot of improvements. But if you go disposable, forget Pampers and Huggies unless you don't like money. Walmart generic is garbage - but Costco (Kirkland) and Sam's (Member's Mark) are both very good. Walmart potty training pants are the best value. Breast is best, but do what your wife needs to do. Breast or bottle, get a Snuggli. Its a C-shaped pillow that fits around your abdomen and puts the baby in a good feeding position. Helps to feed them no matter what the source, plus you can prop the baby up (back or front) on the floor with them laying on the pillow. Clothes - Once Upon a Child -Forget any other store. High quality (and some lower) used kids clothes up to age 12 or 14. They also have new stuff. Saved us millions. They also have a good selection of used strollers, pack-n-plays, etc... They occasionally have had "dollar" sales and we left with a ton of clothes for a mere pittance. Strollers - look at the wheels! Little wheels bad! The bigger the better. In Europe, strollers have huge wheels and have great mobility. The US seems to be obsessed with small wheels for whatever reason and they stink at going anywhere that isn't hard and flat. Here's hoping you are naming the boys Pauly and Robin!
