Mrs Milk suggests commencing with two bars a day to boost supply and thereafter maintain by enjoying one bar daily for best results. You may feel satisfied by the first evening, or it may even take a few days before you notice a boost in milk supply. Some mothers may take up to a week to notice a marked difference, whilst others may not experience an increase at all! Each body is different and responds differently to various foods. However, Mrs Milk granola bars have already successfully helped many mothers to substantially increase their milk supply.
