Teething symptoms for almost 1 month but still no signs of any tooth yet?

[Carmen2]

I thought DD was teething when she was 5 1/2 months old because of these signs:

bad nappies giving her a red bump especially after a poo
number of poos increased (about 4-5 times/day) where it used to be a maximum of twice/day
drooling (in the very beginning, now it has stopped)
constant smacking of lips flicking her tongue up and down to rub her gums
chewing on teething toys
very whinny
sleeping habits changed completely
not wanting to eat solids
drinking less formula


She doesn't have any temperature, thank God for that...

Could that be teething or am I misinterpreting al of this? How long does teething symptoms go on before a tooth cuts out? THank you all for your replies
