Happy Babies vs.. Not Happy Babies?

Mamas.. perhaps Mamas more of multiple kiddos.. do some of your babies seem much more happy, smiley and friendly than others? I ask because a friend of mine has a little girl and she always seems so grumpy and just the opposite of smiley.. all the time! I am just curious as to if these bits can foreshadow the personality of a baby when older.. let me know what you think!

    I had pretty happy babies most of the time ...but my oldest was very fussy and we attribute this to gas. but now she is a very anxious child...so not sure if any correlation?
