Hi i'm new to mumsnet and this is my first thread! I want to know if my little boy is teething. He is 17 weeks old and has started drooling over everything! He also chews anything he can get hold of and has had nappy rash and flushed cheeks. I have read that these may be teething symptoms but i'm not sure. Has any one else experienced these symptoms? Thanks and i'm sure i'll get the hang of this soon :)
