I.S.
My son got his first two teeth around 4 months and they haven't stopped coming! Poor thing has literally been teething since the day he was born! the first two were the bottom front teeth, then some on one side, then the other, then on top, now molars... Needless to say sleep has become a luxury for all 3 of us!
We tried EVERYTHING, frozen washcloths, frozen fruit and veg in food sack thingies, teething toys of all shapes and sizes, topical anesthetics, pain relief drops, lukewarm baths, walks, etc etc etc. The one thing that DID seem to help though was called Dentinox, a sugar free topical anesthetic used by dentists. And frozen teething rings with water, only small ones. The baby sling helped too (Baby Bjorn, thank you we would not have survived the first year without you!).
I sometimes wish he'd had a break between teeth but at least it's almost over! Oh and he's 17 months old now, still has some molars coming through, they're taking their sweet time!
