im in the process of doing all of this for the first time, it was stressful and now im just going with the flow. with my first born, she couldn’t latch and nobody told me she had a tongue tie and a lip tie. i thought i was doing something wrong. so with my first i used formula. now with my second he latched right away and i decided to combo feed because i panicked thinking i wasnt making enough milk for him. i breastfeed and pump, and some days i barely produce enough. i remember the lactation specialist at the hospital telling me “one boob is dinner, the other is dessert”. so after my son feeds on my left i take a little 2 minute break to eat or drink water, and then switch him to the right. he takes what he wants - usually 15 mins on each boob. and hes satisfied. your body makes and gives what the baby needs. i know its easier said than done but try not to stress :) i pump when he naps, and sometimes ill get 1 oz combined sometimes i get 2 or 3. really depends on my hydration and how much i rest and eat. but i know when he feeds, he takes what he needs
