Welcome Lainey. I joined in about April 2012 when I was first told I was to be a Gran.
My 1st GS arrived at the end of September. He is very sweet and now at 9 weeks very smiley and very good at charming by cooing and smiling, but he could do with sleeping a bit more.
It is an amazing feeling to hold your grandchild, and sniff that lovely baby smell again. I cannot stop doing this to my GS's head when I see him and I feel like a mother sheep. You can tell the very new Grans because like me we just keep talking about the baby!
As for Gransnet, search the forums and see what discussion is going on. It can vary from serious poetry appreciation to rather less serous tattoo appreciation. To the just plain enjoyable silliness. There is discussion of all sorts with very little being off limits if you follow the basic rules.
Do be aware of addiction though.
