Hi, I'm not sure if this is normal and I'm worrying about nothing!
My DD went through a phase of trying out sounds/ babbling at about 8 months old. She could do dada, baba, gaga, nana and she could also do those consonants with the ee sound and her favorite sound was Neenee. Following this, she learned to say daddy. This got a positive reaction and then for a while daddy was all she said. Now, she 'talks' a lot but she only seems to have 'd' as a consonant. So she still says 'daddy' and now she does 'doddy' for dog and 'dirdy' for bird. If shes cross she will cry 'deedeedeedee'! Do you think it is a concern that she no longer seems to have the other sounds ?! Thanks!
