This is an exhausting stage especially if you have a climber.
You need to get out of the house. It's critical. Even a long walk is a break from the supervision. Find local playgrounds and visit every day. You might meet nice Mum's too, that would be an emotional support to you.
Assign some toys for outside and let her play out there.
Give her an old spray bottle and fill it with water and a rag to clean windows doors etc, spray plants.
Google easy activities.
But whenever you feel you have had enough, straight into the buggy for a long walk to give your head a break. Maybe download a nice podcast for yourself so that the walk is a nice head break for you too.
Make sure you pick up some Wellington Boots and light rain gear for the winter months so that you can get out in all weather. The likes of Aldi and Lidl do them and they are great to have.
Also try putting her back in her bed more, you need your sleep.
I know it's so hard when they are small but you need to try a little discipline re climbing up and screaming.
She needs to learn the word No. And know that you mean it.
You have my sympathy. It can be very, very hard when you are on your own and no-one is coming into give you a break.
Lastly, see if you can source cheap toddler groups to join. They can be an absolute life saver.
Best of luck. Sounds like you are doing a great job.
