Someone close to me has a DD who is 2. She is very delayed, always has been - didn't start walking until 21 months. She doesn't eat food, just has milk from a baby bottle and sometimes yoghurts and bananas. She doesn't play, talk or do anything. She sits in front of the tv with a bottle rocking back and forth. I've tried gently bringing this up with the mum but she won't listen at all. She does nothing to encourage or enhance development, I do believe she's delayed because she was understimulated as a baby. Even at 4 months she was strapped in a bouncer in front of the tv with a bottle propped in her mouth. What can I do? Can I tell someone? And be anonymous! Please help I don't want to upset the mum but I'm worried about that poor baby!
