Alcohol and feeding question?

I had 1 gl of champagne approx at 4:00pm and a 1 gl of mamosa at 6-7pm. At 11:00 I started to use the frozen milk for his 11:00pm feeding. I thawed out the usually amount he normally drinks but when he was done he was crying wanting more (thawing the milk took 15 minutes, since at 4:00pm I put the frozen milk in the fridge) at the same time I was pumping(my husband was feeding him) so I gave my son some of my milk that I was pumping and he took a litle under an ounce. My question is.. Is he going to be affected by the alcohol? ***Note: From 4-11pm I didnt pump
