Sorry I didn't know how old you dd is now. But my ds is 9 months. I give his in a syringe just the medicine. It is flavored banana (since it has to be compounded-so they just add it then). I just squirt 1/2 ml at a time in his mouth and he swallows it right down-follow that with a little water in same syringe. I use to give it and make sure I feed right after, but I am not as strict about that now. It just seems to fall either right after he ate or he will be eating soon.
Sorry to hear about the ulceration. I thought my ds inner lip was trying to ulcerate the other day, but now wonder if it could have been from his recent hand foot and mouth dx (even though that was 10 days prior).
God bless and good luck
