Thanks everyone for your replies, it's always really interesting to hear the range of experiences people have.
Feeling a bit better now, thank goodness, and thankfully DH is now off for two days, and another day on Easter Monday.
I should have said - i'm genuinely not talking about illnesses you can soldier through - i really can do that, and have. I'm talking about being so ill that you actually don't feel safe looking after your children - eg. not being able to carry baby, or physically get up off sofa if toddler is doing something hair-raising and about to injure self.
I have two children under two, so they are both with me all day - it's not even a case of just about managing the school run and coming home to bed. It's about being hands on, for up to 13-14 hours. I suppose there is naptime, and you can use DVDs/TV to a certain point, and do very basic meals.
DH is certainly not unwilling to help, and did manage to take 1.5 days, but it is just so hard for some people to take time off - he had to have a meeting with his senior boss to explain why he was off, so really felt he couldn't be off again unless it was absolutely unavoidable.
I tend to agree that you should do the very best you can [and i suppose that as a SAHM, you do feel that DH has to keep work sweet as he is the sole breadwinner for all of you], but yes, at the end of the day, if there is literally no choice, no family to call on, what else can you do?
I must say i am impressed at what some of you have contended with while ill - respect to you! And though i am a little shocked at the person who had to deal with DH going back to work so soon after her CS, i do admire her for being able to deal with it. It does seem a bit harsh if you can't even get 48 hours paternity leave? But i suppose some people are self employed etc, and simply have no choice.
Thanks everyone, good to get context as ever. Seems that mums have to basically work til they drop? Nice to be needed and all that, but really... yes, is this what it's come to?
