So if your child's waking up at say 4, 5 o'clock in the morning and you want to figure out how to stop that or put an end to that because that can be really exhausting, I would look to do four different things. One is I'd make sure you are putting your baby to bed or your child to bed early enough. Again, that's very common that we put our kids to bed too late. So maybe somewhere between 7 and 8, depending on their age. And then awake, put them down awake, so that they can learn how to put themselves to sleep so that then, when they wake up at 5, they'll know how to apply that skill. So always think of like for me, if I wake up at 5 and I stay awake too long, my brain starts ticking, it's really hard for me to go back to sleep. So it's important that we know the skill of putting ourself to sleep and back to sleep. The other two things that I would do with your child is I would make sure that they're well-napped. Believe it or not, the better they're napping during the day, the better they sleep at night, the less likely they are to wake up at 4, 5 o'clock in the morning. And then shoot for a window of something like 4 - 5 hours from wakeup from the afternoon nap to bedtime. So if they wake up at 3, their bedtime is something like 7 PM. And then they won't be too overtired, which being overtired will cause them to wake up early. I know it's not logical, but it's absolutely true.
