My little boy is 16 weeks in 5 days. He goes down at night between 8 and 8.30 and this could be him until between midnight and 3am. Some nights he wakes much earlier for a feed, sometikes 2 night feeds then seems to be wakening every hour afterwards. Most parents I know who have babies at a similar age all day their baby is sleeping through. I know every baby is different though. Would be greatful if you could share your little ones sleeping patterns.
