Our 3 year old has always been great with speaking/sentences etc. Over the last few weeks, everything has changed. She is not really getting the sentences out and stutters now and again. Is this normal? We're a bit worried, she won't ask for say 'toast' anymore, she'll just point to the bread and whinge. She also is fully toilet trained but instead of saying "need to wee Mummy", she'll just hold herself and whinge, whilst she is crossing her legs. We also have a 9 month old son who just babbles, could she be copying him for attention? She used to get up out of bed herself in the morning and walk in, now she's lying there (like the baby) and just babbling too. Thanks for your help.
