A warm welcome if a sad one.it is very early days and has to be a case of getting through a day at a time an hour at a time if need be.When my husband died we gave the older grandchildren the option to attend the funeral they wanted too and so we made sure they were involved making it a celebration of his life. rather than a traditional conventional one he was not a conventional person even the funeral car was a friends campervan They had a say in the music and after the service they handed a daffodil to each guest.we then all walked down to the nearby river and floated them down there,which inevitably ended up with wet feet and laughter .The boys picked up on the idea and send things down the river to say hello even the little ones who went born then do it and so have come to know him through the opportunity to talk about him it presents,Usually a stick or clump of grass nothing harmful although he would have been rolling with laughter the time one sent a docked lambs tail.Every year around the anniversary me and the eldest take a daffodil for each member of the family as we are all scattered,and float them from the same spot.Not everyone has a river or wants the unconventional but what I,m trying to say is you will find your own way to help them cope and to remember him in a good way,could be plant a tree or a whole memorial garden start a memory box with them,anything at all but by doing things together sharing the good memory's of him you will cry together but maybe also find the joy he gave you together too.
