Mommies of 8-10 month olds. Did your baby seem to really change around this time? I usually have a fabulous sleeper and all around happy girl pretty much 24/7. Her naps have gone to shit and she's a lot more whiny! She did have her first tooth pop thru and working on a second. It seems to only bother her during the day; she doesn't wake at night. Also, did their appetite increase? This little girl can't get enough of solids AND her bottles!
