DS (9 weeks) has been rather ratty for the past few days - feeding frequently, dribbling a lot, grumbling between feeds - and the HV suggested he has started teething, tho prob no teeth for a while yet. Have got some powders and some gel, but is there anything else I can do? The worst thing is that he's started waking every 2 hrs again at night, just when he's started to go a bit longer . Tell me this won't go on for months...
