Second, two tips more tips from a dad of 5 children:
1. From somewhere after around 1 year: Put effort into teaching sleep skills: I did it by leaving the room after singing and prayer and coming back every 1 + 2n minutes where n is days. (Of course, use your parental judgment.) This was surprisingly effective in teaching them that Dad leaving the room doesn't mean Dad had disappeared, only that Dad is elsewhere and will be back soon. Important: do come back. Use a timer and follow it exactly. Come back even if the kid doesn't cry. It is important that they realize they don't have to cry for us not to disappear.
2. Also, when teaching them to sleep, don't let the fall asleep with anything (persons, toys, food, music, tv, absolute silence) that won't keep all night. We all wake halfway up many times during the night to check if everything is OK. For a small child a missing milk bottle is enough to signal "not ok".
if you've got woods and a camp fire, that little sucker is probably out before the embers die down, unfortunately that's not what the typical night looks like for most people on here, so we improvise
- hot shower (not bath) before bed
- immersion school in another language
- sleep training
HTH, congratulations, and good luck!
