Over the past few weeks Isabella's behaviour has been getting increasingly challenging. The tantrums, though I know are relatively mild, have become a daily occurrence and the general whining has been seriously hard at times. I then remembered about The Wonder Weeks app I had downloaded when Isabella was a little, much more manageable, baby. Back in those days we always knew when a thunderstorm of development was brewing and I prepared myself for a tough few days by organising to meet our NCT friends.
