I am not a planner at all (the cribs barely had sheets on them when the babies were born!), but bottles weighed heavily on my mind for some strange reason. I think I really believed that this was the issue that would make or break me as a mother.
And you know what I've found out? It doesn't seem to matter at all.
We have used disposable bottles from the hospital, cheapie Gerber bottles, Dr. Brown's, Tommee Tippee, and Playtex.
Right now Cole uses Tommee Tippee, and Ellen uses Playtex. (She still takes rice cereal in her bottle, and all the tops we have - needed to shake up the formula and rice cereal - fit the Playtex ones and not Tommee Tippee.)
I like them both fine, but the Tommee Tippee ones are easier to clean. It's just the bottle, nipple, and ring. Easy Peasy.
The Playtex ones have the bottle, nipple, ring, a bottom piece, and silicone piece that goes over the bottom. The extra parts allegedly help air escape and cut down on air the baby drinks in. I'm not sure I really believe that, but whatever.
The bottom line is, in my opinion, the type of bottle doesn't really matter. I will say, though, that some babies seem to prefer one type over another. If that's the case, then choose whatever your child seems to like best. My children have never shown a preference. They, especially Cole, take whatever is put into their mouths.
How many bottles to have is something else I struggled with. My advice is to start out with only a couple of whatever kind you choose. If you don't like them or your baby doesn't like them, you haven't invested a lot. Once you decide which brand you will be using, you can get as many as you want. There is no magic number. Some people get enough for two days of feeding. Some get a million. It just depends. I have 6 of each type. This gets me through a day and a half of feedings. I like this because it encourages me to wash bottles every night, but I don't absolutely have to if I really can't or really don't want to. I'll still have two to start the next day with.
Oh, and you definitely need a good bottle brush. I have killed several and have decided that my favorite is the First Years Double Scrubber. It has a sponge on the top and the bottom with bristles in between. It also has a little thingy that flips out of the bottom to clean the nipples. It has by far been my best bottle brush.
So, there's my take on bottles. As with most motherhood things, finding the right bottle is just trial and error. But don't get stressed that there's a "perfect" or "right" bottle out there for your little one.
For all the moms out there, what kind of bottles do you like best? Did your baby have a preference?
