Keeping older kids busy...

Those with older kids, how are you keeping them busy? I have a very active 4 and 2 year old and I’m feeling really guilty because I’m not doing as much with them as I normally would in the summer. I’m averaging around 4 hours of sleep at night with my almost 3 week old and I just don’t have the energy to do much. And my daughter (the 4 year old) is constantly asking what we’re doing, where are we going, etc. I really do try, if it’s nice I’ll walk them to the playground, yesterday I made beaded necklaces with them and we coloured, we’ve baked muffins, etc, but then she’s bored again and is at my heels constantly. And then I get frustrated. 😒 I do have her enrolled in a couple week long day camps, but the next isn’t for another couple weeks. Ughhh, it’s been so hard! Please tell me I’m not alone!
