Hi dobbie,
Just do what feels comfortable for you. Many JW's celebrate holidays to a certain extent. At Thanksgiving and Christmas our family always got together to have a traditional meal with all the trimmings. My JW mother gives birthday presents. This has caused some problems with my sis in law. Her family is not JW and told her parents they can't give the kids bday gifts, but my JW mom does! Go figure.
While I would LOVE to have a Christmas tree and string lights etc, hubby still doesn't want to. We have some close friends we exchange gifts with and attend Christmas parties.
The expense can be handled. There are all kinds of homemade gifts you can do - gift baskets etc, and make sure you set a budget!!!
Things take time, so don't rush into anything before you're ready.
BB
