Ah, OP, when you said 'baby' I wondered if you meant 'newborn baby' and I see you did!
Take my advice and do not do anything for him at all until you're starting to feel like yourself again. Trust me, it will not make you feel good. When you're so tired and your entire world has been rocked, you cannot afford to give anything away without resentment and especially to your partner who supposedly is equally responsible but of course is nothing like equally affected.
Do not even make him a cup of tea. You will be filled with rage when he either doesn't thank you for it or maybe only drinks half the cup and you'll be furious because HE should be making you tea, and now the fucker's not even drinking it?!
In my head the things I did for DH when I was postpartum should have elicited the reaction 'wow, Tot must really love me to do this even when she's just had a baby and would so much rather be sitting down. I feel loved that she made the effort.'
But the actual effect, I have come to realise, was more like 'oh, cool, Tot's doing tea again. Must be back up to full strength! Business as usual then, maybe I'll organise a night out...'
Just don't do anything. I wasn't consciously 'being a martyr ', I was trying to offer a gesture of love and generosity but yes, they fully take it for granted and you will be pissed off forever more. I still am, well over a year down the line. And i think this whole effect is magnified with a second child because you're acting as normal as you can for your first child, but your DH, poor simple fool, is also deceived.
