Please do not worry too much! My son had this same situation. Around 8 or 9 months he became more introverted and did not smile, wave and laugh as often as he used to. He seemed like he suddenly became a very serious baby. In my moms club play group I noticed that he was fussy, did not want to play with the kids and was not happy like the other kids. He seemed to fuss at every little thing when playing with other kids. My son also never crawled and cruised very little so of course I was a little worried as he is my first child as well and I was worried about him meeting his milestones. he took his first steps at 15 months, then would only walk if I held hid hands. At 17 months he was off and all over the place. My son is now 19 months and he walks, run, laughs, dances, talks, plays, sings and LOVES kids. He is shy with some people but evev that is no where near what it was. He hated little gym bbut loves music class, you should try a music class or something that fosters him at his own pace. He is just on his own time clock and he is just fine. Please respect and enjoy your sons little personality, he just needs this time to absorb the world around him. Now that my son is older I see that all kids have their own hang ups and their own gifts. But so much of my worry was pointless, he is a happy and delightful little boy. when I read your post it reminded me so much of how I felt. It will be ok and do not let any one tell you he is autistic or delayed or grumpy, he is a baby!!!!! (I am a LMFT with extensive training on early child development and am not a fan of the lay person making comments about children who are sensitive) I did choose to skip the MMR until my son is 3 or 4 just because I felt like he was showing some flat affect and social delays so I wanted to see if they would go away as he matured versus blaming the MMR. I am very happy with my decision to delay the MMR.
