It's the time when the meaning of happiness shifts and you feel that happiness is when your child is sound asleep or gives you the cutest of smiles. When happiness is when your child doesn't struggle to breathe. And when happiness is when your child only cries when he or she is hungry, and not because something else is wrong with your tiny little human.
I saw people actually laughing at the thought of someone finding the constant stream of motherhood challenge selfies upsetting. I saw them calling them horrible, unkind names and even posting links to a satirical story referencing 'childless infertile women who should be banished to live with wolves'.
No matter what we're striving to achieve, yearning for or worrying about, we can be our own worst enemies so women need to stick together - in person, at work and on social networking sites. Choices and experiences around motherhood are hugely emotive subjects naturally, but we only lash out at each when we're feeling sad, uncertain and insecure (oh, and tired).
Facebook's "Motherhood Challenge" which has hit in the last week or so has caused some controversy. The challenge (and it strikes me that it is not particularly challenging at all) is to post three photos which show how you are proud to be a mum and then you "challenge" other women whom you think are great mothers to do the same.
Well I got a whole lot more than I had anticipated when I managed to wangle 24 hours away from my loved ones this weekend. I set off to join the inspirational Molly Gunn, founder of the Selfish Mother blogzine and 24 other (non-pregnant) women who had let themselves off the 'leash' for a day at the spectacular Rathfinny Wine Estate.
When I was a little kid nothing would excite me more than when we were out and about and I set eyes on a very special poster. My stomach would bounce with joy at the sight of that special white basset hound dressed in his matching blue sweater and bobble hat, licking his lips and clutching his overflowing cardboard cup of blue raspberry icy slush.
I used to be reasonably fit. I am vegetarian, have practised yoga for over a decade and have always been naturally slim. When I had my first child my body stretched and strained but within six months of a natural birth I returned to a slightly heavier, slightly hippier, saggier-boobed version of myself. But not that dissimilar.
Forget night feeds, tantrums and potty training - my number one parenting struggle is trying to navigate the constantly conflicting emotions that any mum or dad faces every single day. This is the side of parenting that nobody warns you about, presumably because it is almost impossible to explain to non-parents.
