My DS is 9mo, and I think we've only had about 2 days in the last month where he's been 'happy smiley baby'. Instead we've had 'grumpy grizzly baby', and neither of us are very happy with that!
I know he's doing lots developmentally around this age, as well as teething, but it's messed up his sleep and ruined his appetite. And I won't even mention the separation anxiety... 
Can anyone reassure me this is all normal, and give me an indication of when my sweet giggly baby might return? This is so much harder to manage than when he was newborn.
Thanks...
