My daughter is 18 months old and I don't think that she is as far on as others speech wise but I don't have many friends with children so I don't actually know.
She definitely understands everything that is going on and understands things like ' take the book to daddy for a story' and she will.
She knows loads of animal noises, can say ball, baby, again, hi, bye, uh oh, daisy for Upset Daisy on in the night garden, and tries to say makka pakka!!
She isn't putting more than one word together though, and surprisingly isn't saying 'no' but she does shake her head instead.
Does this sound normal?
