Hello, a few nights this last week by 6.5wo has went for longer stretches sleeping during the night (4.5 hourd and tonight almost 6). Until now she tended to wake 3 times at least. Is this ok in terms of feeding, we are EBF? Will it affect my milk supply, should i be expressing? Baby is well and healthy in herself and her weight so i didn't think waking her to feed was needed (its not every night but becoming more frequent).
