May I know what chocolate is a booster for breastfeed?

hmm.. I'm not sure if chocolate is regarded as a milk booster. Some of my friends actually avoid eating chocolate. Because, apart from caffeine, chocolate also contains a substance called theobromine. It is a stimulant that has a similar effect to caffeine and is linked to causing gas problems in babies. White chocolate contains lower amount of theobromine and may have fewer side effects on your baby. So, some of my friends who opt for that or milk chocolate if they have some cravings.

Hope this helps!
