Please help me with a minor argument at my house. The situation is that I am going to Spain to my mum's house for two weeks in summer with my two daughters. DH doesn't come with us, this is fine, we have always done this.
By coincidence my brother has announced he's getting married one week after I come back to UK (I come back 3 Sep, he gets married on 10th). So we will need to return for a weekend there, and DH will come with us.
When the wedding was announced my mum offered to look after DD2 for that week so she doesn't have to come to UK and go back. DD2 was 3 in April, so she'll be 3.5 in Sept. I thought it was a good idea, it will save upheaval (no much money really so that's not a factor) and she will get an extra week of holiday. DD1 has to come back to go to school. DH thinks she is too young to be on her own, away from close family and she will think she's been abandoned while older daughter is preferred.
We go to my mum's very often, three times a year for a week or more at a time, so she knows the place and she likes it. She loves my mum. I think that past the initial moment of anxiety she'll be fine and that actually she'll have a really special time with her grandmother.
This is not a big argument, we are just not sure what the best thing is. What would you do?
