It really is a discomfort, a lot of sleepless nights. Teething pain remedies varies from child to child, I think you should try and see what is suitable for your child . One thing is for sure most gels are short term solutions. Here are a couple of long/short term solution:
1. Massage- rub his gums with a clean finger firmly and gently, in the beginning it's a bit uncomfortable but later he relaxes more.
2. Anything cold- you can freeze terrycloth toys, wet washcloths,teethrings, applesauce,yogurt, grinded food-make sure they are not solid frozen and too hard for the baby. Also beware of giving the child something he can choke from.
3.Long term-Infant Tylenol ,ibuprofen,advil, pain relievers will last for a long time 6-8 hours.
Relax the baby rock him and comfort him to get his mind off the pain.Give him a warm bath before he goes to sleep cover him tightly. After a good night's sleep, you will find your baby is better able to cope with the distress of teething and you will be too.
