My DD has always been fine in the car and car seat until last week when out of nowhere she has started crying and arching her back to resist being put in it. As soon as she’s fully strapped in though she’s fine so she’s not uncomfortable or anything like that. I’m the only person that ever puts her in it and nothing has happened that she might be scared of or anything like that. It literally happened overnight.
Any ideas? Anyone else been through this and it was just a passing stage?
