Maybe this has been the problem. Rookie mistake. I will continue like this and see if it makes more sense now. THANKS for your help as always
Nice! Seems like you're on track. You can get plastic syringes in most pharmacies. They're super cheap and they hold a decent amount 5ml+. I think i ended up using my son's old syringe once his medicine for his last cold was used up.
