DS was so chipper this morning, laid in his baby gym gurgling away. Getting him dressed and talking and smiling and all good. Then without warning a shriek at the top of his voice and he's been moaning ever since! Not necessarily crying but moaning about it and when I pick him up he flails one arm about and as he needs his nails cutting is scratching the crap out of me.
How can they go from so happy and smiley to bloody angry for no particular reason??
