Where has time gone?? 6 months & growing!!!

Wow, Colin is 6 months already! Yesterday we went for his wellness checkup! The doctor was very happy with everything he is doing and how he is growing. She said that he will be do pulling himself up, crawling and saying mama and dadda hopefully soon! I can't believe how big he is getting! I am so loving this stage though, except we are having a hard time sleeping through the night, other than that we are doing great! Dr. Jones said that when he got sick 2 weeks ago that threw his schedule off and you just have to get him back on it, she said to try letting him cry and put himself to sleep.... I tried that yesterday and it didn't work, after about 10 min. I went in and got him and rocked him to sleep, then at 3 he got back up and I let him lay there and cry to see if I could do it:) He finally after 20 min cried himself to sleep! It killed me but he was fine.
