I'm so worried as my 3 month old has started screaming when I take her anywhere. I realised she may have decided she didn't like lying down so have tried taking her out in the car seat but it only makes a tiny bit of difference. She lasts for about 15-20 mins, starts looking uncomfortable then starts crying. The amount of times I've ended up carrying her home while pushing an empty pushchair is ridiculous. Usually by the time I get her home, she's in such a state, she falls asleep. I can't bear seeing her so upset so it's making me not want to leave the house! Any advice/suggestions welcome... What could be the reason for this?
