As a mum, I wanted a carrier that was comfortable and easy enough to do by myself. I went to the Oxford street store and tried on a few other brands and as soon as I put this carrier on, I knew it was the one I wanted. Firstly, this carrier doesn't have push clips like the others and this made the biggest difference because I found with the the push clips, I was faffing for too long trying to clip First Time Mum · johnlewis.com

I purchased this a few weeks ago after struggling with my other child carrier for so long I was deterred from using, which in turn negatively impacted my ability to be/feel productive throughout the day while also taking care of my baby. This is everything I hoped it would be: easy to put on and use; comfortable for baby and I; adjustable so my husband or MIL can also use it; and supportive. For r Han5 · lillebaby.com
