Ye betul tu! Playpen memang bagus untuk encourage crawling dalam safe space, especially kalau rumah banyak hazards. A few of my mum friends juga guna playpen untuk practice milestones macam ni sebab anak boleh explore freely without worry. Tapi make sure the playpen itself is sturdy and meets safety standards ya, sama penting juga ensure the floor inside is soft enough untuk baby's joints. Alhamdulillah kalau dah jumpa product yang work well for your little one!
