This carrier is amazing!
It's a fantastic quick and easy one shoulder carry, with lots of adjustability to fit your baby or toddler well:
You can carry one baby on your front, or once they can fit their legs around you, on your hip - that's usually around 3/4 months.
You can also clip two together to carry two babies at the same time - making the Lenny Twin!
Please note, that if you're after the Lenny Twin, you do need to reserve two Lenny Hips to make this.
They work from 0-24 months, although 16 cm is the minimum width of the panel, so if your newborn likes their knees closer together than that it still might be a bit big for them.
