Grandmother's coffee

Grandmother's coffee, what a great idea! Surprise guaranteed!
Offer you mother a package of the famous grandmother's coffee, or just hand it to her saying "I got you some coffee!" Or, you can wrap it up as a present for a special occasion (birthday, mother's day, Christmas...).
If she does not understand, point to the word 'grandmother' on the package. She will certainly be thinking about you and the baby every time she drinks coffee...
