my daughter is now at 4. she usually woke up 1-2 times to drink water before age 2. after 2, she could sleep well the whole night.
my son is now almost 1 year old. he also woke up 2-3 times a night for either drinking water or hunting for care but usually could sleep again within 30mins.
since 2 mth ago, he always kept turning around and woke up at abt 2:00am. orginally, we didn't want to feed him milk at such time. eventually we gave up after spent almost 2 hours to make him sleep. once feeding him milk, he could sleep again. we wonder he may be hungry, so started to feed him rice instead of congee from 10months. situation was improved a lot, only 1-2times woke up but falling into sleep again after drank water.
according to book states, don't expect the kid can sleep well before age 2. my experience tells me seems it is right. so it is already luck if your kid does not wake up too much frequently and able to fall into sleep again eaily.
My daughter(3 yrs) always wake up at 2 to 3 am. Sometimes, she ask for milk and snack or want to go out to watch TV. We also consult doctor about her sleeping habitat (cannot let her take afternoon nap, otherwise she will sleep at 3am), it seems we cannot do anything. We tried different methods during these 3 years. If any moms have solution, pls le me know!
