I thought the same and almost gave up on it.
I had to deal with that problem since I was 13.
I have raped and murdered that problem now.
But now is not the time to fix it for you Earl because your little girl is still very little and probably cries a lot at all random times.
You need to focus on improving your sleep at whatever time you get it.
The best Earplugs in the world are called "Cord Max Extreme".
They are comfortable and block a lot of noise. I don't hear the neighbors child crying when I use them and a ventilator next to my head is only half as loud.
That is a 100 pack, I recommend that you do some research to find a 10 pack (which will be enough for a year).
Well she actually sleeps through the whole night. The problem is that I end up getting to sleep about 5 hours before she gets up. So I just need a minor tweak somewhere so I can squeeze an extra hour or two of sleep in. An idea that I thought of is to get a nap when she takes a nap. But idk since I can usually get a good chunk of work done during her naps.
You need to wake up early and wake her up at the same time.
If you wake her and yourself up at 05:00 she will probably be dead tired at 20:00, that means you will have to go to sleep at that time as well (or at 21:00).
You will get plenty of sleep if you manage to do that.
