We are expecting LO2 in December, and I'm trying to think of all the stuff we'll need to prepare. With LO1 we used pampers newborn diapers, similac formula, tried several different types of bottles, etc. I'm wondering if we should try alternatives to what we used before. Diapers and formula are so expensive! I'm going to try the up & up brand formula this time around. Maybe even the kirkland brand.
