Hi,
It might not be easy but get help from anyone you can, his mother might be a pain but she has been there and done it before. Just don’t lose your temper with her and push her away, just calmly explain how your feeling and that you can use her advice but at the end of the day its your baby and you must make the decisions.
If you push her away she wont be there to help when you need her, and judging from my baby you will need all the help you can get.
I know its not easy and raging hormones make it more difficult
