My husband and I have one DC together who is a baby and he has older DC from a previous relationship who are 7 and 11.
It's half term this week and he's WFH as it's our week with DSC.
I find my husband can be a bit smothering in making sure everyone is included in everything and it's especially suffocating on school holidays because DSC are here all day and I feel like I can't leave the house without taking them.
Basically I just want some time alone during the week with our baby like when they are at school and he at work and so I've made a few excuses as to why we need to go out some of the days DSC are here. Mainly things like telling him a group we usually go to is still on when it's not so I can go for a walk / park with DC without everyone tagging along or that I have a dentist appointment when I don't.
I know it's not great to lie, but I don't know what's worse, saying that so I can keep my sanity and leave the house by ourselves some times or telling him I don't want to spend all week with his kids!
