Quoting Mama Lizzy :]:" Things got easier for me when my son started crawling....he would always cry for me to carry him around ... [snip!] ... would try to crawl from 2 months and would get so pissed that he couldn't. He started at 5 months . Congrats to your baby!!"
Same here. DD would scream bloody murder if I wasn't holding her. I swear she started crawling (4 1/2 months) and walking so soon (at 9 months) only because she got tired of me "walking away". That and the fact that her two older cousins would constantly walk away from her so I'm sure that was some motivation for her to get up and learn how to go! lol
