On the day, we're going to an event with both our DCs. It's something we often do as our OH aren't interested and glad that they don't have to go. His day will consist of leaving home at 7am for work, rushing home to collect Dc and straight out to meet me and my DC.
I always take snacks for the DC, usually something I've baked. This time I was thinking of making something birthday themed. Basically, I suppose my question is would his wife think that was weird? I'm really thinking of it for the benefit of the DC and maybe they will sing Happy Birthday, but is that my place/would it upset his wife?
IMO opinion he should be spending his birthday with his DW anyway, but she's apparently fine with it and he wants to go to the event.
