Is it normal?

Melissa

So we are trying to get our 19 month. Sleeping in her bed in her room. Some nights are better then other. So last night it was a great night she slept 6 hours by herself in bed without me going to laying next to her. While tonight was bad. So first she did want to go bed. So at your bed time. I went and layed with her. It took 40 mins to go to bed. Then 3 hours later she woke up screaming. So took back to our bed. Is this normal? I’m trying so hard and I’m losing allot of sleep. 😭
