Your cutie pie has a lot of body awareness now and can point to most of his body parts when asked. By this age most kids are able to name about 10 of their body parts. He would also know what most of the body parts does and will also be able to tell you when his ears or legs hurt, etc.
What you need to know
Keep repeating the names of the body parts during the day, especially during the bath time. This will help improve his vocabulary even further. Make sure that you now use the right names of the body parts rather than baby names that you may have given to them earlier.
