Sarah is currently growing her lower cuspids.
The new tooth is not fully grown yet. I observed that the growing pace of the cuspids teeth is the slowest among other.
Maybe due to this Sarah is feeling uncomfortable lately. She also had been easily frightened by all kind of things. She has less appetite in drinking milk, but luckily she still likes other food.
I normally will feed her with gripe water every time she is growing teeth, but she doesn’t like it plain nowadays. There for I have no other option than to mixing it with her milk.
