My baby is 14 weeks and never been keen on his pram. I've tried everything I can think of including, putting a comfy liner in, propping him up with a wedge pillow, making sure he's not too hot or too cold. He's better than he used to be but he will still only tolerate it for 10 minutes at a time. Is there anything else I could try?
I do use a sling at times but it's not always convenient when I'm on a dog walk.
