So turns out she has a chest infection. On antibiotics. She did a sneeze this morning and the poor thing had streams of snot coming out.
She is happier during the day but as soon as she lies down she is miserable. Not great as you cant sleep standing up!
I bought some rice and oat milk today from supermarket (thanks Jols -cant believe how many different choices of milk there are) so I will give those a whirl.

Thanks again for everyones advice. No CC for us this week. Lucky I am on holidays
