Because of ds's chest problems it is very difficult to impossible to fly with him, as it aggravates things. We are going over this month in the car (all of us), but then the next holiday we can do that won't be until next April, which is a long time. My mum will come over at Christmas, but then it will again be four months until April, and my mum is on her own and my dad is in a nursing home with end-stage Alzheimer's. So I've been contemplating to take the dd's over in Feb half-term for a few days,leaving ds with dh and my MIL. Would that be cruel? Ds will be 20 months then.
