I purchased this but was only able to use it a few times, so I'm listing it in hopes that someone else can use it! It comes with a head support pad, so it seems usable from before your baby can hold their head up. I will wash it before sending. For usage instructions, please refer to the product website. https://search.rakuten.co.jp/search/mall/CLIVIA/412209/ *The last photo is borrowed from the product website.
