6m not eating?πŸ˜“

Stacy
Is it normal for a 6m old to hav an "off" day? Im a ebf ftm and just started introducing solids its been going well i think. But this morning when i nursed at 640 she suddenly pulled away and threw up a lot! She didn't seem distressed. And all day she only ate once more at 1130 she refused to eat anything at daycare. it is now 440 she refused the breast at daycare at 330 so i came home. When she wakes up im sure she will be hungry!! Anyone else experience this?? Thank youπŸ’–
