Seeking Advice on Bottle Nipples
I have a 4 month old breastfed baby boy. He is fed by bottle during the day at daycare. All of his bottles currently have stage 1 nipples (Born Free). Is it really necessary to move up to stage 2 at this point or can I continue to use stage 1 nipples until he is 6 months old at which point I would switch to stage 3.
