My gift to my mum was actually from my kids (it was a sign that said "What happens at Grandma's stays at Grandma's". Mum gave me a present for mothers day "from my kids" (so they handed it to me but it was bought by her. I bought a present for my MIL from my DH and the ids, the card was for "Nanna". Don't see the problem with grandmothers getting/giving gifts.
