Hi Thanks for posting your query. There are few problems expected during teething like irritation, excessive cry, excessive salivation, diarrhea. Constipation is as such not noticed during teething. But, stomach upset is expected due to infection as child keeps sucking the things due irritation in the gums. Even cold is not directly related to constipation. It would be of great if you provide me some more information to guide you better. Since how long your child is having constipation? Did constipation start after introducing any weaning food? Is she on any formula milk? Constipation could be due to intolerance to some food especially milk. It is more with formula milk compared to breast milk/cow milk. Introducing fiber-rich foods into her diet, such as fruits, vegetable purees and cereals like porridge will help. Fluids are equally important and the baby should be given plenty to drink for example water and diluted fruit juice. Massaging the baby s tummy can help relieve some of the tension in the bowels. Consult your pediatrician to rule out stomach infection if the above mentioned treatment doesn t work. I will be available if you have any followup queries. Thank you consulting me. Wishing you good health. Regards, Dr. Jyoti Patil.
