[Mere_de_Jambo]

Jambo vomited in the middle of the night and it was clear liquid. It did not have an odor and looked more like water. He is 7 months old now. He had vomited what looked like snot once in the middle of the night when he was 31/2 months old then a week and a half ago he vomited clear liquid during the day. It isn't something that is frequent or on a regular basis as this happened exactly 2-3 times in his 7 month life. He eats raw (pre-made frozen) and veggies. I feed him liquid supplements (dropper):vitamin/mineral, immunity, and skin/hair/joint. Is this something dangerous or has anyone else had a similar incident?
