I keep reading he should be able to have 2 hour wake windows by now, but once he's been up an hour he starts getting really whiny and upset and goes straight to sleep if I put him down for a nap... He can nap for around 1.5hrs (obviously sometimes they are shorter), so it's not causing rubbish naps particularly. However he's still waking at least once a night for a feed and a couple of dummy replacements - could this be caused by not enough wake time?
He's generally happy, alert, growing and feeding well and hitting milestones, so I'm not worried about a health problem, just what it's impact on sleep might be. Do some babies just have shorter wake windows?
Thanks!
