I'd like to say more words about the baby girl as I couldn't edit in the above reply.
It's my fault that I thought that only a few inch drop couldn't hurt her as far as she still could drink her mommy milk so I took her to the vet too late.She breath by mouth at that time.I took her twice. The first time the vet said that she's only hungry so I had to feed her myself every 30 mins or 1 hour. So I took her home as the vet advice. I took her back 2nd time about 2hours later as I saw her doing worse. This time she couldn't make it.She died before we arrived.
