Reaction to strawberries?

I’ve started introducing food to my 6 month old.

We’ve so far tried oatmeal, banana and carrots and shes been fine.

I gave her some strawberry to try earlier. She was fine for a few hours, now I’ve just tried to get her to bed like normal and shes hysterically cried for over an hour, inconsoleable, I’ve finally after over an hour of constant crying and rocking her in my arms got her to sleep.

She’s never usually like this, usually goes to sleep in her cot relatively easily. Could this be a reaction to the strawberry i gave her a few hours ago? Or would she have reacted to it straight away? Shes got no other symptoms of a reaction.

I’ve been worried about weaning as she cant handle lactose so I’ve been nervous about introducing foods and maybe worrying over nothing.
