My LO is just over 4 months old and we BF well with cereal in the morning and evening (recommended by my midwife) and a very occasional bottle of formula. Lately, she's been STTN (12 hours, no dream feed). I've heard that night feeds are important for maintaining supply. Is that only true for the first few weeks or will the lack of night feeds reduce my supply now? I love BFing, so I don't want a reduced supply forcing me to stop.
