What weight limit should I look for?

Most basic bouncers cap at 20 lbs, which many babies hit between 6 and 9 months. If you want a seat that lasts longer, look for models like the BabyBjörn Bouncer Bliss (29 lbs, converts to a toddler chair) or the Ingenuity Keep Cozy 3-in-1 (up to 40 lbs in rocker mode). Reviewers with bigger babies on r/bigbabiesandkids specifically flag the 20-lb ceiling as their main frustration.
