4 day old baby, trying to bf (have managed so far but it's not easy is it?). Am ordering NUK glass bottles for the occasional expressed bottle, from amazon and have no idea what size and type of teat. Assuming latex? Size 2? Baby was 6 lb 8 oz at birth, has a good strong suck but is lazy latching. I think 120ml bottles will be fine for now.
Would appreciate teat advice please.
