Struggeling with new baby and toddler!

Abi • 22- Mommy to baby Hugo 06.03.19👶🏻💙

Hi all

I recently had my second baby boy who is now 2 weeks old and my 22 month old is good with him most of the time but since baby has come he has started smacking and especially when I’m feeding new baby.

I take it this is an attention thing but any advice on how to discipline a little one who is still under 2? He doesn’t listen to ‘no’ if anything he does it more. He is golden the rest of the time it’s just a new habit he has.

Thanks all!
