Normal amount of sleep for 20mnth old? used to wake up about 4 times/night to nurse but this past week she has slept from 11pm-9/10am. naps: 2+ hrs

Yes. Success!: We (doctors, moms, dads, neighbors, etc.) all want babies to sleep through the night after they are 3 months old. Parents with babies who sleep through the night are lucky parents. As long as a baby is growing fine on his measurements at the check-ups, and is healthy, parents don't need to wake up a sleeping baby at night, and don't have to wonder if the baby is sleeping too much or too little.
