My 3 week old has only just got back to his birth weight, having only gain 2 oz in the last week. Hv is happy to give us another week before referring us for failure to thrive. He has 2 bottles a day and bf every 3 ish hours during the day. At night after the bottle he goes 5 hours then 3 hourly again. He does lots if wee and poo, and although he sleeps a lot like any newborn he does have awake time, is strong in his arms and legs and screams loads having his nappy changed. Any advice or experience to share please. I an happy to ff rather than bf,, if that is what it takes
