My DH wasn’t I’ll but was extremely busy at work (engineer, so always under pressure, and it was yet another period of redundancies happening).
Dd has silent reflux so threw up almost every feed, which was only DD’s at her 6 week check (gp was no use on it). And as we later learned, she’s also hot ADHD/asd (Asperger syndrome end of spectrum).
Family live 2.5 hours away.
So it was very hard. DH did some feeds when I could express for him, and he tended to do some middle of the night nappies and/or sheet changes.
There were easier days and harder days. There still are in some ways (she’s 14).
Do what you MUST, no more. Food on the table, keep kitchen and bathroom clean (for everyone’s health), ask for specific help from those who offer (please hoover sitting room/hang laundry/bring a dinner etc).
Use shortcuts - convenience food (within restrictions for DH), use tumble drier for drying or even send laundry out to be done at dry cleaners/laundrette. If possible, get extra clothes so laundry is less urgent. Don’t bother ironing, just clean and dry is what’s important.
And sleep. While it’s not possible all the time, have at least a sit down with tea and food or a nap if possible, when baby naps in the daytime.
Buy ingredients that are already prepped - carrots already peeled and chopped, frozen veg, diced meat. Make dishes that need a small amount of prep and then long slow cooking in the oven that you can ignore - stews or small roasts. Or take 1 nap time to make a spaghetti sauce for that day but a larger pot than usual so you can freeze some for another day.
When you are about to give a bottle, make a cup of tea in a travel mug, so you can also have a drink while feeding the baby. Get in useful snacks in the shopping for you to grab on the move. And speaking of food, try and get online shopping for basics or for meals (see if there are local restaurants doing proper meals as takeaway at the moment).
[Hugs] you’re not alone. The problems change. You get periods of peace and calm. As baby grows, they are less dependent on you for every little thing.
