So what are the actual rules on drinking and nursing ?

Last night i went out around 1am i had half a cup of tequila and spirt gave it to my friend than maybe 30mins latter drank not even half a margarita i got home around 3am and about 3:20 i started pumping because i was leaking alot i pumped 10oz i dont want to throw it away i have it in my fridge right now but what should i do? Keep it ? Dump it ? What will happen if i feed him it ? :(

BTW i never once felt a buzz i felt completely sober
