recently, she also sleeps less than 10 hours every day that made me worried ... and she ate a lot ... she will be 34 months, but only 86cm tall, how about your daughter?
hobby , my girl's case similar to you and we go back to the 健康院 for further checking. But My girl is worse than you because she not only sleep less (10 hours a day) but also eat little (although her weight is porportional to her height). So 健康院 says she may need to see 營養師 as well.
