I have two DSC aged 7 and 9, a 6 yr old and a 2 yr old, as well as being pregnant. When we have DSC and go for days out it is inevitable that DH takes the older DC off and I'm generally left with the 2 yr old, and soon the baby too. I don't necessarily mind this, as obviously the age gap means they have differing interests/ability to go on rides/do activities etc.
However, I don't like travelling long distances for a day trip because our toddler doesn't like travelling one bit. She can be distracted for about 45 minutes maximum then screams and cries. I spend all journeys occupying her and its no fun at all. She then will fall asleep on the way back, which means a late night for DD and I and me subsequently having a tired toddler to deal with the following day.
DH wants to take the DC to Alton Towers this week, which is two hours from us. We went in June but camped overnight before and after and I know from then that the queues are long and DD wasn't really fussed about any of it. I said to DH that because of DD not liking travelling, because there was over an hour queue just to leave the car park last time meaning she'd sleep from 6.30-8.30ish then be woken by the other DC and be up ridiculously late and because DD and I wouldn't see him and the other DC all day, that we may as well just stay home. He says he won't go if we don't but I really don't see the point - it's a lot of hassle for DD and I and realistically makes no difference to everyone if we're not there.
Am I being unfair by opting out of days like this? How do you manage age gaps between DC?
