Correcting Dh’s grammar in front of dd because she’s starting to pick up his way of speaking.

[CocoDeMoll]

I’m not a snob in any way, seriously!!

My dd is 5 and she now attends a little local primary where there are lots of kids from v MC backgrounds and I don’t want her being picked on in the future because she says things wrong. And for the record my own spelling and grammar is shit so I’m not judging.

She’s says ‘them’ instead of ‘those’ as in ‘can I have some of them tomatoes’ and other stuff like that because dh does. Dh doesn’t realise this isn’t correct but doesn’t jump down my throat if I say it isn’t so he’s pretty decent about it. I have no issues with accents or dialects but I feel like down the line she might get further ahead if I correct her from saying stuff like ‘so I tells him’ to ‘so I told him’. AIBU?

Oh, send. Sorry. I'm not a native English speaker...

Just a thought... You don't necessarily have to be 'obvious' about correcting your DH or your DD.

A well known form of correction is to repeat a (corrected) word or phrase back to a child.
E.g. If your DD says "I bringed the bag to you", you could say "yes, you brought the bag to me, thank you".

This strategy could work with your DH when you're in front of your DD, avoiding scenarios where you outright say "DH, that's wrong" which could feel undermining to him.
