Blueandpink - totally in the same place as you. Mil was meant to be coming to see the dc today but couldn't because of the weather, and I was really gutted.
Love being with the boys, and I run a wee (very wee) business cause don't have time to expand just now so was going to do some work today, but when mil couldn't come, in my head I should be able to think of lots of fun things to do, but I just can't.
Went for a walk but they got cold, played with the railway and that was fine, but overall, they had far too much tv today.
I still prefer working from home, and some days are better than others, but I find that the days we have a planned activity (like a toddler group) are much easier than others, and also having a bit of a timetable, like for example, 9-9.30 play with trains, 9.30 - 10 read stories, 10 am snack and drag it out as long as I can.
Don't usually spend e whole half hour doing the planned activity but it at least gives a bit of structure to the day instead of looking at 8 or more hours till dh gets homes and having to fill in the full 8 hours.
Also, if you can, have at least one day/evening where you do something with friends or just you outside the house. Even if it's just going to the library to read a good book for an hour in peace, or go for a coffee with a magazine, a swim, anything really that makes you feel like you are not 'just' a mum.
