My 6 week old daughter hates her car seat and cries when she's put in it. It has the newborn insert but she just seems really uncomfortable. She hates the straps which are by her ears. She also hates having her head messed about with- trying to get a hat on her is heart breaking. She was a c section birth, small at 4lbs 15 but is now 8lb12. someone suggested osteopathy but I have no experience of this. It's getting hard as I use the seat a lot on the pushchair. It took 2 and a half hours to get out today as she was so upset.
