Agree with all the PPs, you are being a great mum! Don't say otherwise

My niece is 11 months and doesn't deal well with being out and about either, she won't sleep in the pram, cries in the car, sounds like like your DS! My sister even said the same thing you've been saying, she's a bad mum and shouldn't even be going out etc etc.

It seems to just be a stage she goes through every now and then. You are right, it could be teething. Be patient.
