Can Beer Affect An Ear Infection If Having Drunk A Half Glass Of Beer Would Affect My Baby At This 4 Month Stage Of Pregancy?

If having drunk a half glass of beer would affect my baby at this 4 month stage of pregancy? - can beer affect an ear infection

I went to a party and drink a half glass of light beer. I think its fine. But I read the replies are not allowed to consume alcohol. Does it affect my baby, I could drink beer during this time?

What is the best diet for 4 months pregnant am I?

Thank you for all your responses.

Thank you.
