What happens if your breastfeeding and bottle feeding and drink one bottle of mikes lemonade something like a sminoff can i pump the next day?

Yes: There is essentially never a need to "pump and dump". Your "milk alcohol level" is essentially the same as your blood alcohol level. So within 1-2 hours after 1 drink, the alcohol is gone from your milk. The amount of alcohol that gets into the milk is very small, and should not affect a baby under normal circumstances. So the occasional drink is fine.
