SO won’t pay for any baby stuff

I’m 36 weeks and my SO hasn’t paid for anything. Either everything was free from the baby shower, samples I’ve gotten from different companies, or diapers or clothes I’ve paid for.

I don’t know the gender but he does so today I nicely suggested that he goes purchase a few baby outfits and hide them so once the baby is born we have outfits instead of just white onesies.

I told him once the baby is born I’m not going to want to go to the store to go shopping so it would be nice to have something already.

He said, “that’s your job.”

It’s getting frustrating because he hasn’t paid for a single thing and I don’t want him getting used to thinking everything baby related should come out my pocket!

I mean he hasn’t even offer to pay for anything. I’m getting annoyed because I feel like once the baby is here I’m going to have to do everything.

Update: the baby is his. And he works
