Oh I feel you OP. When I had my DD last year in March 2022, all we did for months was sit on the sofa, and watch below deck whilst she contact napped. Sometimes we would go back to bed and sleep for 3 hours. Nothing would get done until bed time lol.
What I would say is get yourself into a routine. Soon as baby wakes up, feed & change and put in bouncer and bring them into the bathroom with you. Shower, brush teeth & get clothes/comfies on. I did this every day as it brought routine to my mornings
Once that's done most/every mornings you'll feel so much better and won't feel as bad about sitting about most of the day. At least you've showered and changed.
My LO at that age loved Ms Rachel and she currently loves Sing & Learn. Or when I really needed a distraction coco melon. Oops😂 we definitely don't watch that now.
Don't be so hard on yourself. I think staying at home with a toddler is 100x harder than getting up and out.
I would recommend sensory activities like water play, sand or stones in a bottle to use as a rattle, play dough, painting, musical toys etc. if you haven't already join a baby class. Meet other mums and yoir LO will love it!
