I also used a version of Glenda's hold down method but I did it a bit different. I don't know how old my was when I started and it might be too much for a 10 month old though. Maybe you could save this method for later on if you still have problems. FYI, I only had to hold my son down once. I told him he was going to take the meds one way or another. I let him choose. After the one time I held him down he always choose to take it like a big boy with a sweet snack and water immediately after he took the meds. I would also tell him that I knew the medicine was horrible but he still had to take it. That I would get in trouble with the doc if he didn't take it and I was not going to get myself in trouble. But like I said this might be too much for a 10 month old.
You said she only drinks water...Maybe add it to her water. Put only a small amount of water that you know she will drink quickly. Maybe you can sneak the meds in under the radar this way. The water might taste a little funny but maybe she will not be able to figure out what's funny about it.
My second child has special needs and is partially feed with a tube so I'm spoiled with this one. I put the meds directly into his stomach. I forget what the average mom must overcome. I wish you good luck and patience!!
