A change of pace I hope compared to some step parent posts.
I have one ds who I save for sale out of my income. He's only a toddler but I save very regularly for him, I'm hoping this will be used when he's 18 for driving lessons and if enough some money towards his uni fees or rent of first place etc etc.
For my dsc neither dp or his exw save forthem at all. Their choice but they do get birthsya/Xmas money on both sides and pocket money from exw household weekly. They don't get pocket money from dp but some money eg if we go away on holiday etc as spends. The dsc are 9, 10 and 13.
I've suggested rather than pocket money here, as we only have them eow and one or two nights a week that dp saves a set amount evry month for driving lessons or similar.
That way one parent is doing everyday pcoket money and the other saving for a future expense to benefit the children.
Obviously dp would have to do this and I'm not getting involved beyond recommending it and helping set up accounts or similar.
Does that sound like a good idea?
