Teething at 4 mos?

My Little Man was a 34 wkr and is now 4 months, In the last week he's been really cranky and nawing at things and not wanting to eat so much. He has a bad cough though too so I'm debating on what it is? Him teething or ear infection? Should I take him in to be seen? Any thoughts/sugg. would be appreciated...

riley got his 1st 2 teeth around 4 months now he will be 2 new years eve and has been teething his 2 yrs molars for about 2 weeks now it is hell lol

by 4 months my first three children all had 3 teeth my youngest got them at 5 months

oops 2 teeth i mean

Easton started teething at 3 months he had his first one before he turned 4 months and his second before 5 no. He never had any problems with them, but now he's been workin on one that is giving him hell, I feel so bad for him
