My baby now needs bigger bottles but these are these 4oz bottles that lasted until the bitter end of this stage and I think that counts for something.

It's so nice to pump into these using the Duette, then have one ring that can accommodate either the silicone storage cap or the nipple if you buy that separately. So much less to wash.

Such a great deal! Bought these dome caps from Amazon and they shrunk after sterilizing to work with the bottles with nipples!

I like that these bottles are PPSU, making the leeching of microplastics when heated much less of a risk factor. My little loves the nipple, and we don't run into breast/bottle confusion.
