If you asked me this last Friday, I would have said yes.
This morning, hell no! 
DH been away, both kids been sick, my hyper emesis has flared, I've had no sleep and had hysterics from both of them as soon as they set foot in the door.
They are 4 and 2.5 years, which I think is a tough period. 4 year old settling into school and is exhausted, 2 year old is in tantrum central and I'm pregnant with number 3.
However, when I not sleep deprived, sick, pregnant and feeling like death, the answer must be yes. As we got pregnant on purpose with number 3.
Regularly think we are mad to go back to the baby stage when our two are becoming much more self sufficient - but I think motherhood is crazy!
Once DH is home, I've had some sleep and TLC, the answer will be yes again.
Life is very full with them in it, and very full on.
Hardest thing I have ever done, but I'm not sure what else I would be doing either.
I know in about 8 years I'll get a lie in again, and will be able to lie on a beach and relax without having to constantly entertain toddlers.
Although then I'll have a teenager, so I might want the baby days back!
It's complicated, but overall, yes I would do it again X
