By TC do you mean Tung Chung? I think whether or not you enroll your daughter in school depends on so many things--but mostly her personality and what your goals are. My son was enrolled in nursery school when he was 2-years-old and started kindergarten this past autumn before he turned 3-years-old and it has be great for us. He's a very high-energy child who needs a lot of social interaction and stimulation and where we live, he wasn't able to really get that (very few children, no parks nearby etc.) so kindergarten is a really fun experience for him. He goes half-days, comes home eats lunch and takes a nap and then spends time with us (mom and dad) in the evenings. It works really well for our family--especially since I'm working outside the home and we have a 2-month-old who also needs care.
Whether she'll be behind or not is hard to say. If she has plenty of social interaction and learning opportunities at home and with friends then she probably won't be behind. There are local families who choose not to send their children to kindergarten at all and then they just start primary 1 when they're 6-years-old. I have to say, though, that generally, the children who don't attend kindergarten at all (the ones I teach) don't adjust as easily to primary school life and can be behind in their language skills (English and Cantonese). If you're able to provide enough stimulation to help your daughter develop in key areas (numeracy, language, social skills) then she'll likely do just fine when she starts school.:gl:
