My DD is 16 weeks and 95% bf, she has one bottle before bed and I can't usually get enough ebm to not have to top this feed up with formular. The last few days she is wanting to feed pretty much every hour after mid day, last night she woke after I'd been asleep for an hour and she fed for an hour 1/2 then didn't settle until 3.30, then woke again at 5.30 and I lay in bed with her and she has been feeding one and off until 10 am, not crying but making loads of noise. I try and co-sleep and feed after she wakes, which has been at 4 am, but it's now getting earlier and earlier and she doesn't fall back a asleep but just wants to feed for hours - If I try and take her off she roots to get back on and I am on my knees today with sleep deprivation. Is this a growth spurt which might not last for weeks and weeks, and could I add another bottle into her day or use hungry baby feed to cope with this and hopefully get a few more hours sleep?
