Hi Linzi,
I suppose this is a tough one cos as with babies, toddlers develop so differently.
Joshua is 15 months old and is walking and climbing up the stairs and onto the sofa, opening every drawer cupboard available. He can say mumma, da da, nana, ta, hi ya, yes and no. If you ask him a question he will say yes or no but he doesnt understand what he's answering too, eg, i asked him if he had been painting today at nursery and he said no when he had been lol! He turns to his name, if you ask him to bring you something he usually does unless he wants it for himself! He's at nursery and seems to play with other kids ok, he was pushing another lil joshua around in a car the other day it was so cute! If you ask for a kiss he opens his mouth and tries to snog you. He can feed himself a yoghurt an most of his dinner with a spoon or fork but it takes a while and can be quite messy. He waves goodbye and claps his hands but doesnt know his body parts even though im constantly singing heads shoulders knees and toes!
I would say Joshua is quite slow with speech compared to my some of my other friends' babies but im not worried cos i know he can hear fine and he is only 15 months lol!
Can your friend see the hv for hearing checks or just a general development review...you never stop worrying do you! Im hope everything is fine im sure it will be xxx
