A few signs:
Baby Food....I finally figured out that the crying that has recently started during meal time (as she use to sit happily in her exersaucer in the kitchen) was because she wanted some TOO! You can see her red eyes from crying to join in. It was an impromptu starting of solids-- grabbed some applesauce from the fridge and ground up some oats in the pantry.
Sitting in stroller without baby carrier...she's been enjoying the view
First ward camp-out and in a tent... I'm pretty sure she slept better than I did. I kept waking up to make sure everyone was tucked in their blankets and sleeping bags.
New found fear of vacuum and hair dryer... not sure when to vacuum now: when awake and terrified or sleeping and bound to wake-up from noise?
Diaper bag full of baby toys that she now enjoys to play with... the trick is keeping the older kiddos from taking them over.
Addie is nearly six months and so much fun. She seems to just be waiting for anyone's attention to give a great big smile! =)
