I haven't read all the replies yet but I wanted to add another side to this ... My 1st 2 pregnancies I worked, did everything at home and with the kids. We moved both times I was heavily pregnant and I unpacked EVERYTHING and built all the furniture myself. I was constantly told I was doing too much but I didn't listen and ran full pelt with everything I did.
This time I am not working, well I'm a stay at home mum to a 4 yr old and a 2 yr old. I am mentally and physically exhausted. I WISH I could be on my feet all day running around after the kids, come home clean and have dinner on the table ready for 5pm every night but I can't. I feel like utter shit constantly. I can easily sleep from 9pm - 8am and then be so exhausted by 1.30pm that I need an hour on the sofa. I have SPD too so even walking my daughter to nursery is agonising. I am used to getting up and doing what I want when I want but it is genuinely a physical impossibility at the moment so my hubby has to help.
Please don't think everyone in these kinds of situations are chosing to be lazy, some of us would absolutely love to not have to rely on others to get things done. It is demoralising and depressing to not have full control of what you can do and when.
