Gift for grandma

Okay ladies I need some quick help! In 2 days me and my husband and our 2 month old are moving from California to Tennessee. My mom is absolutely devastated and has been crying for weeks. We are super close and this is her first grand baby and she sees her at least 2x a week and now it will be months in between visits! I want to get her a meaningful gift before we leave but I have no clue what to get her! Any ideas?!(:
