Rant. Mum keeps commenting that I’m spoiling my baby??

I'm so sorry you are experiencing this. Especially when its still early into your post partum, it can really affect your mental health. I know the tight feeling in your chest all you want to do is scream and run away. Babies before the age of 6 months do not know that they are a separate body from you. Hence they don't have separation anxiety yet. They are literally one with you! I faced the same problem and caused lots of fights and tears. What really helped me was prep talk before going over to their house and in the event a unnecessary comment arises, I got up the courage and said nicely and in a joking manner, "ehhh I sayang my baby soooo much, Nvm I want to hold him" saying this in a happy and playful tone with a big smile. I hope it gets better for you dear. ❤️
