Chocolate Makes Happy Babies (and Moms!!!)

Perhaps it's just that my master's work has taken over my brain but I have begun to look at pregnancy research.  I came across this study which just makes me happy:

In case you'd just like to read a short synopsis:

They had 305 women that participated in the study. They grouped them into never/seldom consumers, weekly, and daily. What did they find? That the daily consumers of chocolate had happier babies at 6 months old. They rated happiness by more "positively reactive and active". They argued that it could be that the mothers who were eating chocolate everyday had a more positive sense of well-being. Thus, they passed those happy feelings onto their babies in the womb. A weakness in their study could have been that the mothers who ate chocolate daily were also more interactive with their babies during the first 6 months.
