Keeping a toddler entertained

Our daughter is almost two (just turned 23 months). Shes a really happy, easy-going child but she's never been a great sleeper. For the last five weeks, she is staying up later than ever. People suggest she's being "naughty" but she doesn't throw tantrums. She's happy to go upstairs and lie in bed listening to stories. She could do this for hours. She's just not tired! She's very alert and pleasant. On a bad night, she's only falling asleep at midnight. On a good night, she's sleeping by 9. We have a bedtime routine, she hears her favorite books, she brings her favourite toy to bed but nothing sends her to sleep. I hear about kids her age who are exhausted by 7.30pm and sleep 12 hours. Never experienced this!I work from home so I'm always with her. I'm four months pregnant and trying to keep her entertained and struggling with sickness/exhaustion is hard. I try to do a lot with her so she sees other kids, gets plenty of physical activity and exposure to her other language. We go to dance class, toddler gym, have play dates, go to the park/farm/forest and do a walk every day. We read lots of books during the day. Nothing tires her out!My MIL keeps saying she's very bright and needs more mental stimulation instead. The reason she thinks this is because she could identify the colour of objects at 20 months. In the last few weeks she has started counting to ten which I assume is very normal for this age. In the last few days, we've noticed she recognises numerals. She'll stop in the street to tell us a number on a sign or call out a number she sees on a toy. My MIL is now convinced her grandchild is some child genius - we think she's overreacting and she's 'normal' - and keeps saying things that make me feel like we are failing our daughter somehow e.g. we should be teaching her how to write and making her play a musical instrument (!). When I'm exhausted and she is still lying wide awake late at night, I start to feel guilty that I'm not doing a good job and she needs more than just being at home with me. We've already decided she'll go to a daycare at least one full day from January.Any advice from experienced parents? Any tips for suitable activities I/we could do with her during the day? She's not really interested in toys except blocks and dolls, she prefers books and colouring in. via /r/Parenting http://ift.tt/2eOCAyl
