Second dc. I really don't remember my first being like this.
Dd is 10 days so very new baby but she her feeding habits are baffling me.
She is a complete dream during the day, sleeps most of the time and wakes for food, is winded, changed and falls easily back to sleep. She takes about 2-3 oz of milk at a time. To be honest I don't have her on a schedule, I just feed her when she wakens and I can see she is hungry.
Night time is a different story 
. Basically she snacks right through the night and last night over the course of the night took 8oz of milk. She had a feed at 10, 12, 1, 3 and 5 o'clock. She didn't really sleep at all during this time. She was quite windy but burped eventually.
I remember the first 2 nights being horrific with my son but after that he would wake, we would feed him, out him back in crib and he'd fall asleep easily.
Dd is much more fussy at night but much less fussy during the day than ds.
Is this level of non sleeping at night normal?
Should we be trying to get dd to go for longer spells at. Isn't without feeding? I just worry that we are doing the wrong thing. Making her wait for food would be very distressing for her though and she has the most pitiful howl.
Adding to this I have a 22 month old toddler who wakes at 5am every day.
Is this level of night wakefulness and hunger normal?
