Yeah, I'm just going to add on to the rest of these moms! I have 3 girls, ages 7, 4 and 15 months. My first, Abbie, was crawling at 5 months and pulling herself up at 7 then cruising at 7.5, walking by 9 months (after she started walking she started running and she has yet to stop!!!)Your son will cruise for a bit before he's confident enough to take his first steps, so enjoy this new stage of discovery and accomplishments! My other daughters were pulling themselves up before they even started crawling, which was about 8 and 9 months, but didn't walk until they were a year old (on their birthdays too!!) Each child is different, so be happy that your son's physical development is going wonderfully! And now that he is pulling himself up and may be onto cruising soon, you may want to go around the house again and check up on your baby proofing - you'll be amazed at how much more he can get into! God bless you and your son!
