Advise needed, please! I am not going to be able to give Shelby her 1.5u of Prozinc in the morning because I have to be at the hospital for my dad's surgery at 5am. Will it be OK to miss one shot? I usually shoot her at 7am and 7pm. OR is there a way to adjust her shot time tonight? I feel like adjusting for a 2 hour difference will be a stretch. Thank you in advance!
