Saw some posts saying cheesecake will help booze breastmilk. But is it okay to eat during confinement?

Different people have different milk boosters, but there are some which boost supply for majority of women. For me, I have a daily breakfast of overnight oats consisting of rolled oats, yoghurt, oats plus milk, chia seeds and some nuts in a jar which I put in the fridge the night before. It helps to boost my supply by about 30 to 40ml. You can try out the items in this list and see which one boosts your supply. Yes, cheesecake can be eaten during confinement if you're not strictly adhering to any diet.
