We are thrilled with this carrier! Both my partner and I have used it many times in the last few weeks and our 9.5 week old baby girl absolutely LOVES being in it. It’s been great in the heat but also keeps her cosy when it’s a bit chillier. Getting used to how tight to tie it takes a few goes and is also probably dependent on the weight and size of your baby, but we have only good things to say about it! Everyone needs one! In fact we have two!
