I hear you!!! I agree with catrionalee about the cleaner and when I go back to work in 3 months I will be getting a cleaner once a fortnight even though I will only be working 3 days a week and we can't really afford it.
I am lucky my DH cooks even though I am not working, because I find BF and a toddler and baby really tiring so he doesn't expect me to cook every night, but I just wish he would pick up after himself instead of waiting for the fairies to come and pick up his clothes or put his shoes away!!!!!
I feel stuck in a messy house with no time to tidy and clean and look after the kids.

The only suggestion I would say is doing a list and seeing if he can do some chores and splitting the workload. Can you get someone else at work so he doesn't have to work 7 days, but only works 5 or 6???

Sending you lots of support!
