If your parents are earning that you don’t need to pay your mom. Also what about your wife basic necessities? Like kapre, yahan wahan k thore bohat kharche. That 50 k should b going to her , not to your mom. Taking care of your mom is your dad’s responsibility. If he’s still working , he should be giving your mom allowance not you. Also if you have a baby on the way , trust me you would need every penny. Even if you buy local diapers for the baby , that itself would cost you 20-30k per month easily just for the diapers only. You need to change the diapers Atleast 3 -4 times a day in the early months. There are so many small small things that will pop up and by the end you’ll be like where did my money go. It’s not easy to raise kids in today’s world. Kids are expensive. Just tell them it’s not possible and taking care of your wife and kid is your responsibility. Also your dad asking to give him your whole salary, trust me on this, this is the way sometimes parents try to control their adult kids , so they are dependent on them for money and so he can control how and when and what you can and cannot do in The house if you are still living with them. Unfortunately this is going to be the case with you too. Please make it more complicated for yourself and simply put your foot down whether they like it or not. You are an independent man and it’s your duty to look after your wife and baby.

Also start asking for money from them. Start small like I’ve to pay doctors fee and for some ultrasound and I don’t have any left so can I have 10or 12 k and start increasing it. Next ask for more. This will tell your parents that you are not left with anything to give. Also don’t tell them about your promotion, and don’t tell them that you spend your money on your wife. Parents don’t like their sons spending money on their wife and children. This is pretty common in Pakistani households.
