Refilling your reusable yoghurt pouches is easy! Simply turn the reusable food pouch upside down and open the wide double ziplock at the bottom of the pouch. Once the zipper is open you can spoon yoghurt into the pouch or pour it in (out of a jug or bottle). If you are concerned about making a mess you can use a kitchen funnel so that all of the yoghurt stays away from the yoghurt pouch zipper. Another idea that we commonly do at home when filming videos (but it would also be useful when holding a baby in one arm), anyway.. the idea is that you put the pouch upside down in a glass (with the lid on), open the ziplock and the glass acts like a second hand, holding the pouch still whilst you spoon the yoghurt in. This is what I do when I only have one hand to use for the refill!I also tend to refill my reusable yoghurt pouches in bulk. I'll buy a good quality yoghurt from Coles or Woolworths and will fill a whole 10pk of pouches in one go so they are all ready for snacks on the go. My kids always want to eat when they are out and refilling the reusable pouches one at a time just doesn't work for us. The only time i do that actually is when I've pureed a meal that my toddler refused, put it in a reusable pouch, and given it to her again. Oh and the other time I do singles.. there are two actually. When we go for ice-cream (it is so much cleaner when in a pouch), and when I have leftover smoothie (again, it stops me getting smoothie all through my car, pram, or playroom). Little Mashies refillable yoghurt pouches are compatible with pouch filling machines that are on the market. Our spout is universal so even though we don't think you need a filling machine, our reusable pouches will fit. All of our yoghurt and baby food pouches come with anti-choke lids as standard.
