I am sure like many we own two baby alive dolls...yep..the ones that eat and drink..but we can never find the food for them in stores so we set out to make our own and this is what worked for us.
To make milk~ Use any bottle..fill with as much water as wanted add few squirts of plain lotion and if you want very small amount of yellow food coloring.
To make orange juice~ Fill a bottle with as much water as wanted then add in a small amount of lotion and orange food coloring.
To make food~ mix some baking soda with little water and food coloring of our choice. (green for peas, orange for carrots)
If you do not add a lot of water you can store this play food away for when ever our child wants to play or you can add more water to use right away.
note~ you could use flour or corn starch but I found baking soda was best. Remember to run clean water threw the baby after feeding and drinking to keep him/her clean.
