DD (3) has become a nightmare overnight since her I’ve had her brother a few months ago. She’s gone from a lovely, placid, angelic girl to an emotional wreck.
She loves the baby, and stroked him and talks to him whenever she can. But with me and her dad she is very fractious, has screaming tantrums and has started hitting things (not people) in frustration. She will sob for half an hour and say she is cross without being able to say why. Everything else in her life is the same/nice
Is this normal?! How long does it last?
