what brand of the sling would you recommend? And what type of material?

Hi mommy, Are you in the babywearing Singapore group in Facebook? Do join the group of you haven't. You can try out different type of slings and attend meetups where some babywearing consultants organized. There are slings and carriers for rent too. I'm sure the babywearing experts there can help you find a sling/carrier suitable for you and your precious.
