Also tried dr brown but she does not like either... Pigeon has bpa free (yellow color, super cute and handy),they also have both glass and plastic (i think only nuk and pigeon has glass ones). yes your hubby is right that initially glass ones are better.
as for the teats, change every 3 months if you are using that only. If you are breastfeeding, no need. depends on how often you use the bottles.. you can buy some when it is on promotion. I usually buy extra two sets (total 4) to keep at home.
