13 month old screeching

[Jw35]

My ears hurt, my head hurts!
All day today he's been screeching and whinging over nothing. We've been to toddler group, played outside and she had a nap. She's had plenty to eat, she's not unwell and as at as I an tell she's not teething.

This has built up gradually over the last couple of weeks, my lovely placid baby is a screamer!

It's not quite the same as tantrums (those she falls about crying) but it seems to the tiniest things set her off.
I was embarrassed at group this morning!

Any tips to get me through? Is this about an average one year old?

I will get flamed to this, but I would give some nurofen and see if it makes a difference. My eldest would get like this when her teeth were moving. They wouldn't necessarily appear, but were shifting and moving in her gums.

Thanks for the reply! It's worth a try and tbh I am now wondering if it is teeth as she was slightly sick the other day and she's never sick! Also been putting her fingers in her mouth a bit. It could be teething but not coming through yet! Thanks
