When should I size up to the Kid Lark?Updated 16 hours ago

Many older babies and young toddlers who are under 45 lbs still fit comfortably in the Lark Baby Carrier. As long as the top of the panel comes up to armpits and your kiddo is under the weight limit, it's fine to keep using the Baby Lark. 

Even if the panel no longer comes knee to knee, your older baby or toddler should still be fine in a spread squat position with knees above bum. 

If they're over 25 lbs and fitting in 3T clothes, the Kid Lark may be more comfortable for you both.
