There is a 7 year age gap between DD and DSC, before DD was born we went to safari Park a lot with DSC and also they have been loads with mum (safari Park is relatively close). Since DD had come along we have done family days out to themeparks, family holidays etc.
Due to the cost of living, we no longer have much extra cash for expensive days out, so now tend to do different parks, with a picnic, again as a family.
I really want to take DD to safari park and would love a day out just me, DH and DD as we haven't actually done this as of yet. As DD isn't at school yet we can go on the week when it is cheaper and she is free, plus isn't old enough to go on the rides, again saving money. DH is happy to do this and said he will book a day of work. Obviously we won't tell DSC as they do not need to know, and mum has always said she's happy for us to do things without him, as long as we don't tell him.
However, MIL is not happy, she has told us its not fair, we are leaving DSC out and if they can't go then we shouldn't go at all. She has said that if we do go without DSC then she will make a point of taking DSC out on their own in the future and not take DD.
Now we have no problem at all if she took DSC out on their own as DSC adores nan and doesn't get to see her that often, but what she has said has made me question if we are being unfair not taking them both and if we should just wait until we have money to take both children.
