Hey I just delivered my baby on tuesday May 24.?

hey I just delivered my baby on tuesday May 24. Hes premature so I have to pump milk so the NICU can tube feed him. I was wondering if I could drink if im giving him my milk. I dont mean drink everynight I just mean for one night. Ive gone through so much this pregnancy and I just need a drink or two. However if I can't drink I wont, I wont do anything to jeopardize him beings hes already so fragile.
