ds is 15wks and night times are steadily getting worse instead of better. He goes to down at 6.30/7.00 pm and we wake him for dream feed at 10.30. was excluisevly bf but introduced formula at dream feed a few nights ago. he's always woken once or twice for dummy but the last week its been more like 10 times. he's been in his own room for a week. we've tried to take the dummy off him, took an hr to settle at 7.00 last night and we leave him for about 10min. he woke at 1.30 last night, left him for 10 then gave cuddles etc, no joy. into our bed at 3 with dummy. knackered and can't see wood for trees. any suggestion???
