My 10 months old baby have been sleeping whole day and stay awake at night usually from 1am or 2 am till 5am or 6am and she sleeps the whole day. She thinks bedtime is at daytime. Is it bad for her health? I have tried to change her sleeping patters but i have failed and we live in delhi where her dad works at night and come back in the morning. So all three of hs sleep the whole day. I am just worried if it will affect her health. She takes naps from 7pm-9pm and 11pm- 1 am or 2 am
