DD is 22 months. Was a very early talker, and has been speaking in full sentences for a long time (cant remember exactly but before 18 months). Since Christmas I've noticed a real drop in her speech, she seems to be talking unclearly (I've never had an issue understanding her before) also saying things like ballerinary and mousey which she hasn't previously as well as lots of made up words. Before Christmas she was telling me stories, now she seems to get distracted halfway through and ends up talking complete gibberish. Mixing up 'you' and 'i' and sentences not making grammatical sentence when they did previously. She has no problem understanding or following instructions, is learning and using new words. Her hearing seems fine.
Does this sound just like a phase or am I right to be a little concerned?
It does coincide with a growth spurt, molars, potty training, a marked improvement in her second language. Only other thing of note is that recently she has needed me to fall asleep whereas before Christmas she had no trouble falling asleep on her own.
