less to no poo

my lo is 2months and i realise she is not pooing as often as last time! her diapers are not as wet/full as before realised this when i start to direct latch, i never time how long lo latches but i latch her until she falls asleep or sleeps even after burping. used to feed ebm about 130-160ml previously, and yes it's a lot but my lo doesnt vomit. sometimes even when i feed her 130ml she still cries and sucks her thumb guessing it isnt enough.
