we started with these which you can use to freeze breastmilk, then thaw in a bowl of warm water, then add a nipple and serve directly. saves a lot of washing. i also liked that they are really easy to measure how much you are giving the baby.
they pair with these nipples. (which btw come in multiple flows. start with the newborn/slow flow) they say they are disposable, but you can use them multiple times until you notice the flow is getting too heavy.
we ended up trying a lot of bottles, but liked these the most. they fit with the same nipples above.
if you haven’t heard of the ready to drink formula, it is also lifechanging. comes in multiple sizes. 2oz nursers are perfect for babies. then when he’s older, you can give him 2x2oz and eventually upgrade to 8oz. these are a lifesaver when you’re out of the apartment. they’re shelf stable so you just shake, put on a nipple (the “disposable” ones above fit), and serve. then you can throw the whole thing away.
Conclusion: 1-4 all work together in one system which makes life super easy. it’s also the most flexible system if you’re considering a mix of breastfeeding and bottle feeding. you’re covered on frozen breastmilk storage, feeding in home and on the go. plus everything is super easy to wash in a medela microwave sterilizer bag or the dishwasher when your child is older.
