i dropped 3 feeds over about 4 weeks and didn't experience a crash, am still feeding twice a day so that could be why. but i did get lumpy boobs and mastitis, although i have to say im really prone to mastitis so i wouldn't worry too much about that! the advice i got was it takes your boobs between 3-7 days to adjust to each dropped feed. i like feeding only twice a day, its a nice cuddly feed in bed in the morning and i get to have a few more zzzz's sometimes too. the evening feed is less fun as he is normally hyper and distracted so we just do a little bit from each and then he gets a bottle!
