Don't hate me but my 9 week old baby slept a whopping 8 and half hours last night. She is ebf and i too slept thru the night regretfully so she didn't get any feeding last night and she is already at the cusp of minimum weight she needs to put on (she was 3.850 gr on her 1 month checkup and she weighed 4.470 gr on her 2 month check up so she put on only 620 gr). What i wanna know is if sleeping this long is normal for her age or should i be worried and also with the minimum weight in mind, should i make a point of waking her up to feed?
