Hi, my son is nearly 7 weeks and for last few days I have been feeding constantly. He is very difficult to settle and get to sleep which is part of reason for frequency although he does seem hungry every 1.5-2 hours. Feeds last up to 90 mins and I am exhausted! I'm worried because his poo is now turning green (was yellow and curdy earlier in the day) which I think means too much fore milk? I don't understand as he is on the breast for so long and although is only feeding for a fraction of this time does seem to get several good let downs if he is on long enough. What should I do? Do I try and limit frequency of feeds? Any other advice please!
