Go & enjoy the time with just 3 of you! Don't feel bad, I think it's a great idea to have some special time & I'm sure she'll love it!
I took M out the other week for some cake & a "coffee" while O was at kinder. She had a ball & it was great to have some special time just with her. DS knows about it but he's looking forward to having a "coffee" just with Mummy one day very soon!

I'm rambling now but the boys will be fine, so go & enjoy the time! Xx

Ps. I'll get back in my box and go back to nesting
