Another sahm here. Two dcs 2.10 and 15mo.
Eldest in nursery 2 mornings a week. Just started in sept and it's been great. She loves going now and I know she is getting lots of attention and age appopriate interesting things to do. Likewise I get to spend quality time with the youngest.
I do one hour max of cleaning, putting washing on, bedrooms, whizz of bathroom in the morning around 9am. Then we go out or have someone over to play. They both nap at lunchtime and I use this time to MN, make tel phone calls, do admin, watch TV, chill etc. In the afternoon I normally do indoor activities, drawing, sticking, baking.
House is always clean and tidy and I've always got people over to break up the day. So my mum and sis always stop off if they're passing. I invite my elderly neighbours over once every couple of months. They love coming to see the DC'S. Also arrange play dates weekly either at ours or friends. By 630pm they're in pj's with milk on sofa for tv time while I do a whizz round with hoover and wipe surfaces, prep adult dinner etc. DH is home at 7. Then it's up to bed for lights out at 730.
I struggled so much in the first year of DC2. But now I've got into the gist of it. I'm managing housework a lot better and the little one is walking and eating and in the same routine as eldest so has made it easier.
But it's by no means easy. The constant shrieking "mummy", feeding, nappy changes, trip to loo , tantrums when out is absolutely exhausting. And so dull.
Just remember no two days are the same. You'll have bad days but you'll also have fab days. Simplify housework chores and keep busy.
