My wee DD2 has started to have screaming episodes in the evenings over the last month or so. Nothing settles her, she's better when distracted but obviously very tired and wants to go asleep. When she does she arches and jerks like she has a pain while screaming before calming down again for a few minutes.
She's a healthy, happy, thriving child in the meantime and no major illnesses.
This does seem like completely the wrong age for colic but any ideas what else it could be?
