Melatonin

Try kids magnesium glycinate gummies. I haven giving those to my 4-year-old since she was 3.5 and she sleeps through the night. Though all kids a different. Also though i never did give her melatonin, the only thing i do use but very rarely is the kids dr teals sleep lotion with melatonin.

Yes. My children were approved to have melatonin for a short time. It did not work.

Take her swimming that’s tiring and knocks them out

Just be careful with the melatonin— it’s ok for short term use, but it can lead to dependence, and it does have some side effects if you use it too much. I’d also recommend trying more physical activity, cutting back on sugars, and maybe some lavender essential oils.

What time does she wake up?

I’ve never done it and probably wouldn’t unless there was some kind of disability or medical need that affected things like this.

But also idk if my husband would even allow the kids to take it. Because he took it once and it made him superrrr suicidal. So he’s terrified of it

Melatonin gives me nightmares, so even if I was 100% sure it was safe for such a small child, I wouldn't give it to them

More context? Does she take naps still, if so cut those out. Then try waking her up earlier if need be. My girls wake up at 10a and don’t go to bed until 11p and they sleep 10-11 hrs a night. No melatonin just a strict constant schedule since they were 3m old. They are now; 4 in March. And 3 in September.
Kids rely on schedules and routines. Keep bed time simple, let them read a book in bed until they get tired and go to sleep. Night lights help my kids. They are also in floor beds and are able to play in their room until they fall asleep.
Baths before bed, lotion after with a massage on growing pain spots. Calf’s, arms, belly.
Black out curtains for the windows.
Hope this helps. 💕

7pm is early

Occasionally, but not routinely. Just try to eliminate overstimulation after dinner, but getting energy out physically is good. Also food and what they drink plays a big role..and maybe try skipping the nap?

Is she in school?

I won’t do it. I took melatonin as a child and it gave me horrific nightmares. I took some accidentally recently in a vitamin and genuinely could not wake up. I slept 12 hours and then walked downstairs completely exhausted to sleep even more. Thankful my husband was off that day because I would’ve been in no condition to care for my children. It was a very small dose too. I couldn’t imagine how that feels for a tiny child.

No, would never give them hormones! It also means the body will produce less melatonins over time…

How much day sleep? When does she wake up?
Start with a consistent wake up time, early wake up time! Like 0630 everyday.

Melatonin in the uk is very hard to get. The gp can’t even give it to you. You need a referral from a paediatrician and even then I couldn’t get it for my asd son. I find it strange that there is zero regulation in the US and some parents do seem to give it out like candy.
