Advice for FTM pumping

Hello fellow mommas,

I just had my baby last Monday and I have started trying to pump. It's the best option for us (me and baby). The Dr wants him eating every 2-3 hours, so at hour 2 I start pumping and wake him after pumping 15 minutes (or until tapped out). My milk supply is hit or miss right now, so we supplement with formula too. (don't come for me, fed is best in our house).

Any advice on increasing milk supply? I desperately want him off the formula, but will do whatever is needed to feed my son. ❤️
