I'm 12 weeks with dc2 and have still got general nausea a lot of the time. When it comes to trying to meal plan for the week (before going to the shops) I find myself going Hmmm, I really don't fancy anything at all.
How do you persuade yourself to plan food that you'll have to eat even if you don't feel up to it?! Any foolproof week-long plans for 2 adults and a toddler, generally dd has leftovers of our dinner the following day for her tea as she eats a lot earlier than us. Thanks!
I think I used to think of a few recipes that I knew I could cook easily and were likely to be deemed edible if I was feeling icky.
Also, tended to just buy store cupboard & fridge staples that could be used in a variety of ways - i.e. mince, eggs, pancetta, chopped toms, yada yada. That way I could usually conjure up something remotely appealing each night.
I normally do the same as you and eat with my DH and leave leftovers for the DTs but actually found it easier to prepare a meal after lunch (when DTs were sleeping), and then eat it with them at about 6ish, rather than wait until later.
Also meant I was free to go to bed as soon as DH had walked in the door and I'd shown him his supper!
I usually buy a twin pack of mince and make one enormous bolognaise and then eat what we're going to eat that night (and DC next day) and then I freeze it to make lasagne / chilli / more bol.
Buy a whole chicken and roast it with roast veg or salad and garlic bread / home baked wedges or chips. DD can eat cold chicken the next day with pasta & cheese sauce or bread and butter and cut up veggies?
