Well, I really liked I Don't Know How She Does It by Allison Pearson – so sue me! When I was preparing this post I peeked on Goodreads to see what others thought and was quite startled by how mixed the reviews were.
If you are heavily into motherhood politics, this may not be your cup of tea
But it is well written and, in my opinion, well worth a read.
The same author wrote another book called "I Think I Love You" which I didn't find quite as good.
