Teeth will come out fine. There is no reason to be concerned. These are anyways not permanent teeth. When your child starts eating, avoid too many sweet items as this can damage the teeth. Also, ensure that you start light brushing as soon as the first teeth come out.

Yes, you can. However, do not make a habit of giving it all the time. Also you will have to learn about all the sterilizing requirements for these products.

Hi no instead of teether, give clean cotton cloth refrigerated one for chewing to soothe the baby's gums and pain too and prevent your baby from taking everything in the mouth to prevent infections and diarrhoea during teething

Yes it is completely normal. Some babies get their first tooth as late as 15 months. That's perfectly fine.

Well if he bites u than my dear I don't know what to say but yes if there is some kind of sores are then u can apply any antiseptic cream like boroline. Or there are some nipples cream available in the market that can help you.

Hi yes, give clean cold cotton cloth refrigerated one for chewing to soothe the baby's gums and pain too and prevent your baby from taking everything in the mouth to prevent infections and diarrhoea during teething

Babies change their feeding pattern several times in the first year. This is completely normal and nothing to be concerned about. Try to feed every two hours. Give mashed fruits, veggies, mashed rice, oats whatever you feel your baby is able to eat. Give something different at every meal. Give your child tummy time, some tummy massages, this should help if there is gas trouble.

Teething period starts between 4 to 15 months...

My son too got his first teeth in his 11th month...
Every child will be unique in reaching there milestones...

So don't worry...

Hi teething period varies from baby to baby and may occur between 4 months to 15 months thus don't worry about it, and if stools are watery then give ORS in water frequently in sips in a day
