Hi when did you move your babies up teat size? My little girl is 15 weeks and still on size 1 teat size. I tried her on size 2 last week for a couple of days and seemed to be getting on fine however then was being sick a bit after her bottle (she has reflux but is usually very mild now since using gavison) but got worse again.
it says 2 months + for teat size 2 & she is 3 and a half months now just concerned she should be moving up.
