It’s not as bad this time. I have a 7 month old & 3 year old. Does your eldest go to nursery? Cos that’s 3 days off my mind at least. We can meet one other adult for a walk/the park with our pre-school aged children. So I plan to meet up with my mum, my cousin, a few friends individually and just get out for a walk! Bundle up the baby in her pram suit & get her in the carrier. Or if I’m with my mum, she can pram push!
It doesn’t look like we are limited to our immediate area, so at the weekends, get out to nearby woods, parks with your OH. Do a treasure hunt, leaf pictures, bark rubbing.. go feed the ducks if you have any nearby.
Stock up on a few crafts - my 3 year old loves paint sticks, really bold colours, a lot less mess. She also loves stickers. I’ve bought a big bundle of different themed ones to whip out for an afternoon! Jigsaws, simple games like pairs.
My 7 month old has helpfully just started crawling 🙈 but is easily entertained with a musical instrument, teething toy, foil, a light projector & her jumperoo! & if I need 5 minutes peace, I put her in her sit up seat with a breadstick. Keeps her quiet for ages!
My final tip would be to have some time off at the weekend. My OH & I split one of the weekend days that we have no plans. So this week, was today. OH looked after both girls from 9am-midday & I had a bath, read a book & watched some telly in bed in complete peace. I then gave him 3 hours this afternoon! It really refreshes me, I just need a few hours with zero responsibility!
