Hi Emma,

I gave up carrying my DS in a front sling at 8 months because he was just too heavy for my shoulders.

At 12 months and 12 kg, that is a lot of weight to carry.

Personally, at that age and weight I'd be looking for a backpack carrier. We never got around to using one for DS, so sorry, I can't say if they are any good or not, but I know I couldn't carry a 12kg baby in a sling that wasn't on my back and I am a little bit taller than you. Check the weight limits I can't recall how heavy bubs can get for a back pack carrier.

Good luck,
