I have this page bookmarked (first time mom, can you tell? *grin*) All babies are different, I think each baby takes their time to get going places. My friend told me her son pulled himself up to a standing position at 3 months. Charlie isn't there yet but I'm not worried! My advice is to get your advice from reputable sources. If you think maybe your little one isn't progressing like they should, talk to your pedi :)
I love the quote.. "comparison is the thief of joy" and it's sooo true!
