She used to by remarkably amenable and has been communicating from an early age so was quite easy to respond to. She started talking early and at 24 months understands pretty much everything but suddenly isn't using her words and instead is crying at pretty much everything and seems frustrated. She used to be such a smily happy baby but now is moaning and easily taken to tears.
She is the youngest of 3 (9, 5 and her at 24 months) and they all love to play together. She is always included. There has been no major change in her life or routine. All milestones taken in her stride. She is potty trained (of her own accord) and mostly sleeps throughout the night (although plays us like a fiddle at bedtime ans often wakes at 5am when if she is well I let her cry and she eventually goes back to sleep until 7ish). I don't understand why the change in demeanour? Could it be frustration at not being able properly?
