I only ask as my ds sleep has gone to absolute pot the last few weeks! Previously sleeping right through from 6.30/7 to about 5.30-6. We now have at least 5 wakings some lasting 2 hours!! He normally takes 5oz about 10pm but the rest he's not interested in feeding and either just unsettled or simply wide awake and wanting to play! He has a dummy which normally when popped back in would put him back over but no longer. Starting to run out of ideas. Is it common for this to happen at this age? We had a bit of a regression at 4 months but nothing as bad as this!
