Grandfather in Scots Gaelic

[calanacrafts]

Hi all my oldest daughter is expecting our first grandchild imminately.
My wife is picking what the child will call us, I was thinking I might want to be called in the Gaelic. What is Scots gaelic for grandfather and how is it pronounced.

Gaelic speaker here and catching up
Grandfather=gaelic is seanair= say it=shen-er which also means elder my kids call my dad shenni
Grandmother = gaelic is seanmhair say it=shenuver we also say granni

Hope this helps....
