Bit concerned that my 15 month old little boy seems to be regressing in his speech. A couple of months ago he was copying words really well, as well as Mama and Dada he would say Nanny, Du-Du for duck, Do-Do for Dog, Labbid for Rabbit... but he doesn't really say any of them now except Mama and Dada.
He obviously understands when we talk to him, will fetch specific doys if you ask him, can point out different animals in books, will give kisses and cuddles if you ask him.
He's walking and running, and he's doing new things all the time with stacking cubes and cups, putting Duplo together, kicking a football...
Just worried that he seems to have stopped saying the words like he was.
Any advice or reassurance?
