Parenting views

My husband and I have different views on how to parent and sometimes we fight about it. It’s really frustrating sometimes.

He thinks I spoil my baby too much while I think it’s not possible to spoil a 3 month old. He thinks i nurse him too much, I think he should be nursed on demand. He doesn’t like me to co sleep but baby and I not sleep better that way. He believes in CIO but I don’t.
