I also use Nurophen for teething as it helps with swelling. As for teething gels - if you haven't tried it yet - give SM33 a try. It is stronger then Bongela.

Good luck - we are in the thick of teething as well and the sleepless nights are tiring and frustrating! I've been up with DS just over 3 hours now and he is finally asleep so I'm signing off and going back to bed.
