For the last 3 nights I've been giving him water when he wakes up (its at various times other wise would have used wake to sleep) so far the time spent awake/flat out asleep is still the same - 1.5 2 hours.
he's taking the same volume of water every night and eats and drinks brilliantly during the day.
Do I stick with what I'm doing or try some if your suggestions?
Thanks.
