What do families need ?

Hey! At the moment I'm still on maternity leave and currently thinking of making some extra money that allows me to stay home with baby for longer. I recently moved to a very family orientated area of London. You literally see mamas, babies and prams everywhere 🤣 Just wondering, what business would be suitable ? Can someone help / suggest on things/services parents and children may need, that are not so common ... If that makes sense 🤣
