My son has suddenly started to get very fussy in the evenings. He starts crying almost for attention at first and then it slowly gets worse until he is screaming the house down and then he tires himself out and naps. At this point he isn’t hungry and all of his other boxes are ticked but we have started noticing a very similar pattern each evening. My question is, can witching hour start at 3 months old as he wasn’t like this before now??
