Bought a toddler size tula for my 1 year old about 10 kg, is the size alright?

Nope it is not right. If u see the description, it says 18months and 11kg onwards. 1yo is likely too small for it. But since u alrdy bought, u can just wait it out a little before using it. I have one and it's still big for my tall 15month old boy, also abt 10kg. U can test and see if baby is too small in it. U can try tucking some of the carrier between u and the baby's tummy and tighten and make it higher. By generally, it is still on the bigger side. We bought a toddler that time caz going winter country and after baby and ourselves layering up quite a bit, the toddler carrier was ok. Now back in sg, not any more
