Little Hearts Playroom

Locals with little ones swear by this place, especially when New Hampshire winters make outdoor play a non-starter. The climbing structure keeps the bigger kids busy while the crushed-cereal sandbox is genuinely one of those things toddlers lose their minds over in the best possible way. It’s clean — like, actually clean, not “we mopped this morning” clean — which matters a lot when you’ve got a crawler. Restrooms and a baby changing station mean you’re not scrambling, and the layout makes it easy to keep an eye on everyone without hovering. A solid spot for birthday parties too, and the kind of place where you’ll start recognizing the same Amherst families week after week.
