my dd 17months, never been to nursery, likes watching all the nursery videos. she can read, recognize and repeat the full aphabet, numbers up to 20, and count up to 8. but she is barely calling us. only mama when is hungry or needs help. no papa or anything and she is quite used to play on her own. Very little interaction with other children when she is out to meet others. a lot of time calling her name is ignored. Is it better to send her to nursery? Any advice is appreciated
