Mother in law post on Facebook how she "loves us"?

[Peaches12]

My mother in law has seen our daughter maybe 2hrs worth since August. She seen her for Xmas, then for a short visit in February.
She post all these things about how much she loves my husband, saying his first & middle name. Then she post stuff about how great it is to be a grandma. & has even misspelt our daughters name.

Do I say anything?
All her friends comment things like "wow I bet your a great grandma" & how my daughter is "so lucky to have her"

I asked her a month ago to really start to make an effort in our lives before our second child is born. She contacted us once via text at 11:45pm & never answered the message back
