No baby shower gifts from his family?

Me and my love went to my hometown because my mom wanted throw us a baby shower. It was super sweet and fun. My family and friends bought me and him so many thoughtful gifts and wrote such lovely cards. However its been a month and his family hasn't got him anything. I invited them even though I knew they couldn't make it plus shared our registry info annnnd nothing. Is that normal? Maybe they're waiting till later? I'm not sure what to think of it.
