So bored stuck in all the time

I have a 16 month old son and a 4 month old daughter

My daughter has colic so going out is a challenge to try keep her as settled as possible and then to help my son do things and get about.

The idea of going out without a friend or my partner seems so daunting.

What if my daughter freaks out..

what if my son falls..

what if my son needs help but I can't put my daughter down

What if.. what if.. 😖😖

I do t feel confident outside of my 4 walls but my son is bored of my little activities and I'm also soooo bored.

All week we wait for the weekend to be with my partner and go out somewhere really good.

Any tips? Ideas?
