For the past week, we've been having a hard time getting Brie to nap because of a couple of reasons: (1) She wants to sleep longer on her third nap, which is usually 1:30PM to 3PM, and can't seem to settle down for the fourth (cat) nap usually at 4:30PM to 5PM. For a couple of days we'd try to settle down for the cat nap because she'll be rubbing her eyes and pulling on her ears, but all she'll do is nurse for a while and after 15 minutes of lying down, when I finally turn off the white noise she'd brighten up and she's ready to go out of the room again and play! But instead of being really tired by her usual bedtime 7:30PM, she's overtired by 7PM. What I read is that at around 5 months, the baby will start to lose one nap. But they don't actually sleep less, because what they do is consolidate the lost nap with either bedtime or the earlier nap. I was waiting for that to happen and already doubted we'll be losing a nap until this happen
