We're heading to Paris in July with our 3-month-old baby for a week in July (yes, will be there for Bastille Day). Looking for tips on where to eat with an infant as well as where to pick up groceries. We will be staying at an apartment with an American kitchen and plan to make quite a few meals in. The apartment is located in the 4th Arrondissment, a couple blocks from the Châtelet Metro station. We're willing to take public transportation to markets, etc. for groceries. Thanks!
