Re: Need a rec for a toddler carrier for a kid in the 95th+ percentile...
Kinderpack. They come in different sizes, you can look at their toddler or probably preschool size. You'll be able to wear him easily on your back.
Her website is kindercarry.com
Get one with plus straps if you're at all tall, not just plus size for clothes. I'm 5'8 and need her plus straps. Super comfy & great resale value.
