Hi, can you recommend sturdy, stable playpen for 5 months old n above? Thanks!

Graco playpen is good - but consider getting a play yard instead as baby will outgrow the playpen very soon. Once baby can crawl and climb it's a different story. Haenim play hard is good, but also check out nihon ikuji .... number 1 selling musical plastic play yard in the world. unbeatable quality and safety features.
