41 weeks

Here is what is going on with Noah this week according to babycenter.com;

Your baby's fingers are becoming more agile. By using her pincer grasp — which lets her pick up small objects between her thumb and forefinger — she may be able to pick up a piece of cereal or other small object without having to rest her wrist on a solid surface. (Now that your baby has graduated to solid food, expect plenty of cereal underfoot!)  She's intrigued by tiny things and is still likely to taste-test them. This is fine as long as they're edible and not so small that she could choke on them.  A good rule of thumb is to avoid letting your baby have anything that won't dissolve in water, like a raw carrot or a whole grape. Cooked veggie pieces, cheese, and peeled and cut-up fruit are great foods for little fingers.

By this week, your baby will probably be able to crawl well on her hands and knees, with her trunk parallel to the floor. (Many babies try to crawl before, but master the skill only now. Some babies bypass crawling altogether and go from scooting to standing.) She may even be able to crawl up stairs.  At this age, your baby can sit confidently and may even walk while holding onto furniture, possibly letting go momentarily and standing without support. She'll take steps when held in a walking position and may attempt to scoop up a toy while she's standing, too.  Those magical first steps toward independence — and lots more exercise for you! — are just around the corner, if they haven't arrived already. Most babies take their first steps sometime between 9 and 12 months and are walking well by the time they're 14 or 15 months old.

Crawling is still Noah's main form of getting around, but he gets more stable in his walking every few days.  Every few days he is able to take a few more steps, and his balance gets a little better.  He has been taking fairly long naps lately, 2 naps at about 2 hours each, plus 10.5 hours of sleep at night.  Since he is sleeping so much and so well, I think he must be ready to hit a growth spurt.
