I am an old hand at this one
.
DD improved in the buggy once she could sit up and look out forwards - before it was just a complete no-go-disaster. She slept on her belly, she simply would not be strapped almost flat on her back for a stroll.
She did stop screaming blue murder in the car seat, but she is still a PITA really. Drops stuff and screams until I fetch it, won't sleep, fusses for this that and the other.
She is 2+ now.
Clearly was a personality thing - plus her reflux/MSPI.
She hates being strapped down and these days she stand in the buggy when I push it
, and I let her free from the HC at only 15 mths as she was just crying in there.
I think these may be life's free spirits.......
(((hugs))) ladies. It really is horrid when they are like that in the car
