Lol sorry half asleep . Very grumpy when I walk up . <| sep |> I didn ' t read everyone else ' s posts but your wife can start pumping after she breastfeeds your daughter during the day and every 34 hours over night . That way you can help with feedings overnight so your wife can get a few extra minutes of sleep . It may help to know exactly how much your baby is eating overnight too , she may rest better . Either way , if that what you decide to do , I would recommend using Dr Browns bottles , they vent so the baby doesn ' t have any negative pressure while feeding , much like breast feeding . Source 1 st born was a 31 week preemie who exclusively breastfeed and exclusively pumped until our son was 15 months old . <| sep |> spez has always struck me as a fairly immature person and this just confirms it . remember how much they demonized ellen pao ? how silly that was . she was a professional and did her job as such .
