Would you be annoyed

My SO’s mom and sister both texted him asking what all we need for baby and he ignored the messages. He casually mentioned it a week later and I asked if he messaged back and he said no 😐 I’m a stay at home mom but I have access to our finances of course. Baby is due in 5 weeks and we still have things we need and it’d be nice to have help and know what his family is buying before we buy the rest.
