how to make my baby happy

I think if the baby is able to enjoy someone's undivided attention, he/she would likely be a happy baby. That being said, think it is also important to teach a child to be independent. So a balance is needed and would help maintain the sanity of the caregiver as well. ;) On the whole, lots of cuddles, love, and attention would give a baby the security he/she is seeking and very likely make him/her a happy baby!
