Some parents like feeding yoghurt to their babies. Instead of buying several small containers, consider getting reusable yoghurt pouches instead. This allows you to purchase large amounts of baby food that you can fill these pouches with whenever you need to. This should prove to be more economical.
You will also be able to cut back on the amount of trash that your household generates due to baby feeding. Every bit counts so go with the more eco-friendly route and go with reusable items instead of disposing a packet several times a day.
Of course, you are not limited to yoghurt with this kind of pouch. You can use any type of baby food that you like including fruit-based sauces and homemade concoctions. Experiment with different recipes that you can find online to see what your child likes the best.
