And how old are they? We have been playing around with LO's schedule lately, since she still doesn't sleep through the night. We are thinking she is going to bed too early, or sleeping too much during the day, or both. I know every baby is different but putting her to bed later last night and only having her take one nap (but she slept in until 9:30am anyway, so two naps is hard to squeeze in), helped her to only have one wake up last night! She normally wakes up 3-4 times.
How many hours does your LO sleep in a 24 hour period? So night time sleeps and naps.
