Any idea to celebrate the husband birthday ? Would love to spend some "me" time with him without the kiddos. A nice dinner with nice atmosphere will be good.

Perhaps an overnight staycation at a nice hotel somewhere nice (Sentosa or Clarke Quay, my top picks). You can order room service, eat in bed and watch random movies -- fun, private, comfy and sexy all at once. This way you get to create your own atmosphere, not worry too much about dressing up and it's literally just the two of you :)
