Expert Q&A

 

By John Dorsey, M.D.
Pediatrician

I have 20-month-old twin daughters. I would really like to know how many hours of sleep they should be getting at night. I am fortunate enough that they still nap for about one and a half hours a day. But what about during the night?

Congratulations on the twins. The usual amount of sleep is between 9 to 12 hours at their age. But it can vary within that range.

If your kids are getting less than that amount, they might be on different sleep cycles that interfere with each other's sleep or might be waking each other up. Keep in mind that just because they are twins doesn't mean that they will require the exact amount of sleep or even sleep at the same time.

The nap time is also right on track, and I would expect that you might even see nap time continue to extend to about two hours as the children become more active.
