My dd was three in September, I have noticed her speech is somewhat behind some of her friends but not sure if it’s a cause for concern.
She still gets confused and refers to herself as “my” or “mine” but sometimes uses “I” correctly so will say “mine want a drink”. I have tried modelling it correctly but I don’t think it helps she refers to himself as daddy instead of I a lot.
She also will find it difficult to express herself when I ask questions such as “what did you have for lunch today?” Or “Who did you play with?”.
I should add she speaks English at home but another language at nursery as we live in Europe, I have heard bilingual children shouldn’t have speech delays but maybe speaking two languages takes longer to process everything.
