Here are some glass anti-colic bottle that I personally think work wonders for my baby. They do not leak & he absolutely loves them. They are a bit pricey but if your child has colic, I definitely recommend these.

These bottles are also used to reduce colic, gas, etc and I love them. They come in sets or you can buy them individually. This site also has other products for toddlers as well. Check it out!

This pillow was given to me but I recommend it, if you have a child who is used to being carried or likes being carried because he/she can cuddle with the pillow as if someone is close to him/her and won’t feel alone.
