My 6 months old sleep routine sudden changes, he now sleep in late like 11pm plus and sleep through he night until 9am plus to 10am plus. He is not waking up for milk in between I have to feed him and he will continue to sleep. During afternoon he will be very active but at night he got problem sleeping and that cause him to sleep late .. I try to comfort him but he still don't want to sleep. I guess is due to him teething. He keep bite stuff put inside him mouth and pull in and out like rubbing his gums and bitting on it. I hope it will be normal soon. He used to sleep at 7 or 8pm. And wake up at 7 or 8am.

Don't worry mommy. He will get back on track soon. Make sure he has a downtime before he sleep so he can calm down and relax as it will help him to fall asleep easier at night. Also I recommend applying Bonjela on his gum to soothe the pain.

it does sounds like teething. If he doesn't wake up during the night time, it's ok to let him sleep. teething are painful and he is able to doze off and sleep, do let him sleep! you can try teething gel to soothe the aching pains

sounds like teething. give him sometime it will pass. and routines are ever changing that's very normal. he will go back to his usual routine once the teething passes.
