Diarrhea on 6-month old baby

Hi. Ask lng po. My baby has fever since yesterday. Parang sinat po, nasa 37.8 yung temp nya. Tsaka basa po yung poop nya though i can say na hindi naman sya nagtatae palagi kaso im worried kasi nga po watery. Is this a sign na teething na si baby? Wala pa kasi po ako nakikitang ipin.
