The French playground I've been taking Michael and Amelia to on Tuesday mornings had a welcome summer party so we had a special playgroup in the park with all kinds of activities, bubbles, splashpad, free food and even a fire truck. Amelia got an extra slice of pizza because they insisted on giving me some for myself although obviously I wasn't about to eat it! There was a police car too, but Amelia refused to check it out because she'd "already seen a police car at preschool". (Fair enough!) I'd actually completely forgotten about the special party, so we arrived without hats, sunscreen or bathing suit but we managed anyway.
Kids had a great time!
