My husband mix honey in water to drink accidentally he drops the glass on floor i just wipe it with tissue my 7 month old crawl on that floor and put her fingers in her mouth now i m scared of botulism because water has honey in it?

Infant botulism is not common even if given honey but you can monitor the situation. It would only occur if there were botulism spores in that bit of honey & they had time in babies gut to begin making toxin. If the kid maintains its usual vigorous feeding pattern over the next week you will be past the usual risk period. Share any suspicious change of behavior/feeding with the doc.
