I know all about the looks!
Mine are older now, so it doesn't happen.
But, out of all the looks I used to get over the years, not all of those would've been people being snotty and looking down on me.
In the mix would have been ....
quite a fair few women trying desperately to conceive, thinking they'd give anything to have at least one screaming toddler with them in the supermarket,
some grandparents looking on wistfully, wishing that their grandchildren lived nearer,
parents of teenagers, thinking, I wish mine were still this age, half the time I don't know where they are!
some mums thinking, I remember this...I nearly strangled mine last week when he/she threw herself on the floor in front of the fish counter!
parents of one or two DCs wondering how on earth you are coping so well, when they struggle with one/two,
people thinking give that woman a medal, how does she stay so calm?
Of course, some would be thinking I was a shite mother, draining the world's resources, and some would pity me, but it did used to help to think that there were a fair few thinking I was doing OK!
