7 Months Old! (and Mason's First Halloween)

Technically Mason won't be 7 months old till Friday, so I am a little early.  His sleeping habits are the same but his eating habits are a little different.  He wants to eat more and more solid food and less bottles.  He is now sitting up unassisted with only a few falls and now he is trying to pull himself up a little.  He has tried using the changing table and me to get himself up on at least his knees.  When he had his 6 month appointment he got his first flu shot and some other vaccinations.  He weighed 18 lbs 11 ounces and was 27 1/2 inches long.  He was 47 and 53 percentile on those but his head is 97th percentile.  :)  The doctor says he still looks good and healthy and gave him the go ahead to eat almost anything except of course cow's milk, eggs (plain but can have things with egg in them), honey, etc.  He loves his baby food and will lick something we give him but doesn't like the small pasta noodles we have tried giving him or mashed up real veggies.  He loves drinking out of, chewing and playing with his sippy cup.  His naps during the day have gotten better and longer but he is ( and I am ) in the bad habit of him sleeping in my arms.  Next week we are going to try putting him down for naps in his crib.  He will nap there but only like 20-30 mins.  Naps in my arms last 1-2 hours!  It will be a struggle but I can't hold him forever. :(  Still can't believe how fast he is growing.  Pictures include him with cousins and second cousins at his great-grandma's 90th birthday parts, his first halloween, with Bapa and Mama P's doggie, and just some random ones.
