We currently have a Beco Gemini which is still working for us but getting less and less comfy as LO gets bigger. LO was 19lbs and 30" at his 9 month appointment a month or so ago.
What height/weight was your LO when you switched to a toddler tula? I don't really want to buy a standard just to have to upgrade in the near future.
Thinking about getting the prism for my little dude
