Just wondering what advice you have heard from parents, in-laws or other generations which would be well out now.
My mum believes babies should sleep on their front as then they have to lift their heads to scream loudly making their necks stronger. I pointed out the risk of cot death and she pointed out that 3 of us survived it. She also took to leaving baby downstairs as my dad would fuss at every sound or movement. No monitors in those days!
She is quite accepting that it is up to us on how we bring up our own children but has said it'll all change again after a while.
