Periods can affect your milk supply, but once your cycle passes, your supply should bounce back. Just try to stay consistent with breastfeeding and pumping during that time. Since bottles can sometimes cause nipple confusion, many lactation consultants recommend using a feeding tube or dosing spoon, which you can easily find on Amazon. These alternatives help maintain the latch while supplementing, supporting your breastfeeding journey.
Periods do effect supply, a lot of people recommend taking magnesium or calcium too, although not 100% sure why but I’ve seen it spoken about a fair bit!
