You're definitely on the right track trying to latch him more, he will he able to build your supply a lot better than the pump! You could try fenugreek and blessed thistle, they are supposed to work well together! Also try pumping one breast while baby eats from the other to help the pump pull out more milk during a let down, that way they are emptied more than usual and your body will get the signal to produce more! Keep in mind that water and eating well are helpful for keeping you healthy and feeling good, which relieving stress can improve supply, however those things are not proven to help with supply, breastfeeding women can fast and still produce plenty for their babies, your water and food intake don't generally effect supply. Being healthy, having rest when possible, and relaxing are all ways to ensure your supply doesn't take a dive though, which does help 😊 and as long as your baby is peeing at LEAST 5 to 6 times per 24 hours, you can relax a bit more because he should be getting PLENTY! Peeing and gaining weight normally are both the most reliable signs that breastfed babies are eating enough 😉

Ok thank you I will definitely try that out @kimberlyyyy_the-preemie-mom

Staying hydrated. Eating an extra 200-500 calories of healthy snacks. Blue Gatorade helps me. Oats/oatmeal, homemade lactation cookies. Continue taking prenatals. Water water water!!!
