Breastfeeding help!

Maria • Mom of 2 💙

I am almost 4 weeks postpartum, I have been exclusively breastfeeding since baby was born. I’ve been having a lot of issues with my supply I use to be enough to keep him full for atleast 2 hours. Now my baby seems restless, cranky, hungry all the time. I’ve been stressing out feeling like I am not producing enough. I have tried pumping and feeding him but even like this he is not satisfied he wants more after I give him everything I pump. I have been thinking of supplementing with formula until I can get my supply up. Does anyone have any tips that worked for them? Formula you recommend for supplementing?
