You have no idea how hard it is. Ask someone who has done it -- especially if the father decides to behave capriciously with support, visitation or custody. It can be hell on earth. Buckle your seat belt. There's a lot more to it than pep talks.
I guess I should have given more detail. My 33 year old son-in-law died last month of a heart attack.
"Pep talk" and prayer are about all I have to offer my daughter and grand children in the way of emotional support, we live about 300 miles apart.
I have been to visit with them twice since the funeral and am going again tomorrow for a couple of days.
