My EBF 15 week old, not the greatest sleeper anyway, has been waking once an hour to feed after midnight, for the last 2 nights. It is nearly killing me! He usually goes down happily at 6 or 7pm and then sleeps until 1pm or so, then feeds and wakes again after another 3 hours, then 2 hours etc.
Any thoughts on what might be causing him to wake more frequently?
Many thanks in advance.
