Oh dear God what have I woken up to this morning?! 
Mocking and laughing at someone posting facts and about your childrens welfare. Clearly a few people projecting on here. 
@LouLou2020 please ignore the (few) posters here saying it's OK for your child to not go to sleep til 10 or 11pm, and then wake at 6-7am. It's NOT right, and it's NOT healthy. The amount of misinformation from a few posters saying toddlers/infants are fine to go to bed at 11pm, and survive on 7-8 hours a night sleep, and suchlike is disturbing.
And frankly I don't give a toss what our 'European cousins' think, or what they do.. It's a fact that toddlers/infants need at LEAST 12-13 hours sleep a day.
@HomesUnderTheSpanner
"Many people value family time together with their small children in the evening after work."
So your need to keep your toddler/infant up til the late evening, "because I have been at work all day" trumps their health and well-being? Jesus wept. 
I am done with the bull being trotted out here.
I'll just leave THESE here.
Read them and weep...
This NHS link TELLS you they need 12 to 14 hours sleep between the age of 2 and 5.

Another source giving basically the same info.

And yep, ANOTHER link about the sleeping needs of toddlers/infants. There are plenty out there. Just google it.

A few people can deny it til the cows come home, (and laugh at me, and deride me,) but the fact still remains that children WILL be badly affected by a lack of sleep. And their health and well-being will probably be affected later in life too, by going to bed late at night, and only getting 7-8 hours a night sleep.. (as several of these sources will tell you.) If 10-11am IS your child's 'natural bed time' then you seriously need to question why, and what you're doing wrong.
As I say, PLEASE ignore those posters saying it's OK for your toddler to go to bed at 10-11pm and then wake at 6am. It's not. It's not healthy, it's not good, and it's not 'a natural bed time' for ANY toddler/infant. These posters are just projecting because I hit a raw nerve with them.
Still, I will take the mocking and deriding from these clueless posters, if it means that even ONE mother on here, speaks to a health care professional about their child's lack of sleep and abnormal bedtime.
And as I said, there are plenty of links to information saying your infant/toddler needs 12-14 hours sleep a day. I bet no-one can find anything that says it's OK or normal them to go to bed at 11pm and only get 7 hours sleep. (Well, maybe on another mummy forum where a few of them keep their toddlers/infants up til 11pm 'because that's their natural bedtime' )
I'm done here. And I am hiding the thread now. Have a good day.
