Anyone else have a toddler that doesn’t sleep through the night most nights?

We started sleep training when she was super young, gets put down at night awake and falls asleep by herself. But many nights she wakes up crying/screaming.

She has been teething pretty consistently and has a full mouth of teeth. So I don’t know if that’s been bothering her.

We let her cry it out for 10 minutes to see if she will naturally settle and then go in. Usually change her diaper and give her a little bit a milk and she is set.

I’m pregnant with number two and am afraid that I will have two kids not sleeping come August.

Any advice?

(She does sleep with a noise machine and night light)
