One of the downsides of a narrow based carrier such as a Baby Bjorn Mini, Original, Move, Miracle or other high street brand carriers is that baby very rapidly out grows the carrier in terms of how much support there is for their legs. As their legs get longer and they start to over spill the carrier, their legs pull downward and this is less comfortable for them because their weight rest on their inner thighs and they feel more of the weight of their legs. It is also less comfortable for you, because more weight pulling away from the carrier equals more strain on your body.
Fortunately, there is a relatively easy fix. All it takes is widening the base of the carrier to better support their legs. For this you will need a scarf. Ideally a woven scarf (i.e. not a stretchy knitted one), but it doesn't need to be anything special. It doesn't need to be strong enough to carry your baby - because your carrier will be doing this... simply any non stretchy material will do. Pashminas or rather market stall cheap pashmina knock offs are perfect!
Then you can use your scarf in one of two ways. The simplest is to pop your baby in as normal, and then tie the scarf around the outside of the carrier as shown here;
I love this method because not only does it support baby's legs making the carrier more comfortable for them, it also helps redistribute more of the weight onto your waist and hips and thus really can improve your comfort a lot too.
An alternative method involves putting the scarf first inside of the carrier, as shown here:
I will confess I don't find this method quite as comfortable as it doesn't give the same feeling of waist support for the wearer. But it also doesn't put a knot behind your back which is helpful if you want to sit down while wearing the carrier and also helpful if you struggle mobility-wise tying a knot behind your back.
Either method will give you a little bit more time with your carrier. It will still feel heavier than a carrier with a wider base and a proper waistband, but it will give you a bit more support and a bit more time. Often parents coming to one of my sessions who have a narrow based carrier find the scarf trick gives them another month or two before it starts to become too heavy again. But importantly this month or two gives them time to try a few different options - whether that is hiring a couple of different things or attending a session to try a few options - and ensure whatever they invest in next really works for them and last for as long as they need it too.
If you are hunting for the right next option please do get in touch and I'll be happy to help. In the meantime I hope this trick helps!
