I just got them today and they fit GREAT! And I'll be able to use them for all her cups later on too! (unlike labels you have to stick on) That said, I still can't wait for my mabel's labels b/c I still have to write her name on the caps!
I love my inchbug bands and have had them for a few years. They basically fit on any bottle, sippy cup or straw cup. Both of my girls are off bottles and on sippy and straw cups and we use them all the time so the girls can tell their stuff (I have 2 colors).
Re: Inchbug label bands & Dr Brown's bottles?
I use them on the 4 oz and 8 oz Dr. Brown bottles. I LOVE them and the teachers at DC do as well.
