@Breastfeedingworries Sounds normal to me, and also healthy.
I despair when I see people with toddlers still up at 10 and 11 pm...tearing around the house, screaming and playing and ranting and tearing the place apart. And then up at 6 am. They usually have parents who think nothing of taking their 3-6 month old baby to the pub, and staying til 11pm.
No way can a toddler/infant grow and function and learn properly when they go to bed at 11pm, and get up at 6 to 7am. And no, they DON'T sleep in til midday, if they don't go to bed til 11pm. They will still usually wake at 6 to 7am. But 7-8 hours a night is no good...
They need at LEAST 12-13 hours sleep - as they are growing so fast (should be anyway!) and they are very energetic, and are learning something new every day.
Toddlers/infants who stay up til 10 or 11pm (frequently,) will usually be the most difficult to control, and hard to teach, and will struggle academically later on, as they will be used to getting their own way, and will have spent too much time in their formative years, not getting enough sleep.
Both of mine went to bed at 6.30 to 7pm every night between two years old and around seven years old, and woke at around 7.am. Sometimes 8am. Up to the age of 2, they'd sleep for 2-3 hours longer than that (per day.)
Like the examples of several other posters, mine excelled academically, and have both graduated from very good universities.
Only people whose kids are allowed to stay up til the pubs close will disagree with you, and say this is not right. Ignore those posters.
