5-month-old suddenly very fussy — anyone else experienced this?
​
My daughter is almost 5 months old and was an extremely chill, easy baby until around 3 months. Since then she has become very fussy and difficult to settle.
She cries/screams a lot during wake windows, gets extremely excited, moves her legs frantically, blows raspberries, puts everything in her mouth, gets distracted constantly, arches her back/looks behind her, and seems irritated especially at night. Feeding and settling have also become much harder—she may seem hungry but then fight the bottle/breast or keep moving around.
She is otherwise active, alert, interactive, laughing, making sounds and developing normally.
The biggest issue is honestly my anxiety. I have started watching every single movement she makes and analysing everything, constantly worrying that normal behaviour could be neurological. I never used to find parenting this difficult, and now I feel anxious almost every day.
Did anyone else's previously chill baby suddenly become extremely fussy/active around 4–5 months? And did it eventually settle down? I’d really appreciate hearing your experiences.
