Because of the pain and discomfort, don’t be surprised if your baby refuses to eat.
4. Decreased appetite or refusal to feed. Uncomfortable, cranky babies yearn to be soothed by something in their mouths — whether a bottle or the breast. But the suction of nursing may make a teething baby’s sore gums feel worse. For that reason, teething babies are fussy about feedings (and get more frustrated as neither their discomfort nor their hungry tummies find relief). Babies eating solid foods may also refuse to eat during teething. Source: WhatToExpect.com
Try to keep feeding your baby during regular meal times. If your baby appears hungry in-between meals, you can offer him/her something too just so your baby gets nourishment.
Now if your baby still keeps refusing to eat, call your pediatrician.
A lot of parents have observed this next symptom while studies have shown mixed results regarding this particular symptom. Just keep a close watch on your baby when he or she has a stuffy nose.

Some experts think that cold-like symptoms in teething babies may be a result of a baby’s attempt to alleviate pain by frequently putting their hands in their mouth or start chewing on their toys. These then exposes the baby to more germs, which results in colds.
Just make sure to notify and consult with your doctor if symptoms occur for more than two days.
