We just went through this with dd having pneumonia ... The nurse showed me how to swaddle her in a blanket ... Just like a new born ... Then pinch her nose so she has to breathe through her mouth ... Then just put a little bit of medicine in at a time so she doesn't choke but has to swallow. We did it once at the hospital and then once at home, then when I gave her the choice of being wrapped up or drinking her medicine ... she is now taking her medicine on her own lol!!! It sounds cruel but you have to get it into them and better she couldn't hurt me or herself
We had/have to do this as well as sort of pinch DDs cheeks together to stop her from.spitting it all back out. It sucks when they dont understand they need it and really hate having it hope something works soon!
