I think you need more input from your dh Alishanty because you have a young (17 month old = constantly on the go/ exhausting) child and have no respite from that - not even Pre-School, and you are also pregnant.
I have a 3yr old and 5 yr old. One at school and the other at Pre-School 5 mornings per week.
Dh works long hours so I require him to do nothing during the week - afterall I have 2-3 hours to myself every day (so can fit in chores), I also have a cleaner, a gardener and dog walker! (yes, I'm fortunate I know).
So I do kids packed lunches and cook proper evening meal every night and clean up afterwards.
Do all food and household good shopping.
All tidying around the house.
Pick up the dog poo (my all time favourite job)
Sort the chickens
Top up cleaning (my cleaner isn't particularly high on productivity bless her)
Read with dd / homework
I don't have tonnes to do, but there is certainly sufficient to keep me occupied and I can't often be found on here for more than 10 minutes or so during the day.
Dh does put kids to bed on the 1 or 2 nights he is home early enough, and he is hands on and devotes a fair amount of time to them at weekends.
I have no major beef with him other than I would very much like to hang him by the testicles when he makes comments like "God, the house is always so untidy" (this was said the day after my 3 year old recovered from a 4 day long vomiting bug and I had spent the preceeding few days mopping up sick and washing constantly)
