I think I know the answer to this already! 
My baby is 6 weeks old...we are finding the sleep deprivation is starting to take it's toll.
My OH does late feed at around midnight then I'm up in the night a few times....for example I was up to feed at 1.45am then 3am and then up for the day at 5.45am
My OH thinks we need to speak with the HV or GP about our baby's sleep. He mentioned work colleagues who say their baby only needed one night feed at this age.
One of this friends has a baby the same age as ours and OH says that she is sleeping through, only wakes once for a feed between midnight and 6am
I just told him not to compare to others, plus his work colleagues have rose tinted spectacles as their kids are all pretty much school age now.
If you have a 6 week old, how is the sleep going currently...?
Didn't manage to sign up for NCT & ante natal classes were too crowded to make any meaningful contacts...don't know anyone else with a baby the same age as ours.
Now feeling paranoid & worried not to mention totally knackered!
Any thoughts?
Thank you in advance
