now i know this is probably 'normal', but just wanted to know if there are other mums out there going through long nights too! DS2 is 19 weeks on monday, and is feeding 3-4 hourly through the day and NIGHT. he also has a 'cluster' feed after 2pm bottle, where he wakes from short arvo nap at 4pm screaming in hunger. he then has over 300mls at 6.30pm and then feeds 3-4 hourly through the night again. he has breastmilk through the day (which i express into a bottle) and formula in the night. is anyone out there still feeding frequently? or am i the only one with such a hungry bub?!
