Breastmilk and wine

alexandra
So my baby is 3 weeks and 3 days... i pump breastmilk and supplement with formula... well last night i had one glass of white wine (riesling)... then i just fed him formula thru the night... my question is, my breasts were full and I pumped 4 oz of breastmilk at 12pm this afternoon... so 16 hours later... can I give him this or do I need to dump it????
