Feels like a stupid question.... put my little girl down last night at 7pm she slept through until 6am had a bottle and went straight back sleep, she is still asleep now 10am. She normally doesn't go sleep until between 8&9pm wakes up around 4ish for a bottle and goes back sleep until 9ish... she is teething could this be the reason she is sleeping more? I thought they woke more?
