9 Month Old Baby Toys Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Miss Mouth's is the best-performing 9 month old baby toys brand in July 2026, moving 60,000 units across 1 ASIN for 35.3% of Top 10 volume. Infinno follows with 30,000 units (17.6%), ahead of TOHIBEE on 20,000 units (11.8%).

With 8 brands splitting the Top 10 and 64.7% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $9.98 to $27.99, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B097B3K46R booked 10K units at $8.49, with ▲ 25.0% MoM change. On the growth side, B00MYWGTGQ leads positive momentum with ▲ 100.0% MoM growth on 6K units, with B09PDPYC2T close behind at ▲ 100.0% MoM on 6K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
