A standard working week is only 40 hours but caring for a baby plus housework, cooking, shopping etc amounts to far more effort than 40 hours on your part. Not to mention the impact of interrupted sleep on your energy levels.
Indeed. How many hours per week do you estimate you spend caring for your little one single-handedly, op? Pretty sure his contract will also include all sorts of leave allowance too, won't it?
Pp are right of course, your partner isn't an occasional babysitter, or a 1950s husband. Caring for his child is as much his responsibility as yours. Alright so baby maybe more attached to your right now (normal) but he should be supporting you in every way he can.
It is a very tough time, of course, for all mums but that doesn't mean you're not up to scratch for struggling. The point is that you cannot be expected to care for your baby, who relies on you utterly, while also running a household single-handedly.
It's time he stepped up.
If your partner won't (and it is wont here, not can't ) then now restrictions are easing if you can lean on friends and family for help please do so. In fact, do so even if you're partner does face up to his responsibilities - you need (and deserve) a break!
However you're feeding baby, then please don't allow mum-guilt prevent you from adapting to new feeding methods to make things easier. If you're breast feeding but bottle feeding will make a difference, then please don't rule out a change (or even supplementing) because you feel guilty. Too many mums crucify themselves over such things!
Also, remember, however hard and awful things feel right now, this will pass. It will get better, and you will feel rested and like yourself again
