Teething baby help

[Diy2019]

Ds is 4 and a half months, he got his bottom two teeth in the last month. I thought he'd have a break for a while before the top ones come through but no, I can see one of them about to come through.
He's so upset, my older ds was never this upset when teething.
What do you find actually helps to soothe them?
I'll try anything.

Teething granules from Boots.

Calpol when really bad.

Rub on gels were useless for us.

Baby toothbrush coated in dentinox for them to chew on exactly where they need it.

Exactly same for us, his bottom 2 came in about 9 months now hes 11 months and the whole top row coming at same time, hes mega upset and bites his gums and they bleed to. He gets lots of relief from.

Mini milks
Calpol
Cold water
Teething granules
Dummies that are in shape of gums that he can chew
Dummies that you can put cold fruit inside

As above, teething gels useless for us to. We also tried those mits that they put on and chew but he just keeps biting his own hand and crying! Bless him
