Ok boy, let's see how you're measuring up. This is the best past-time of new mothers to passive-aggressively say, "my child is better than your fat ugly baby." lol

Ok let's have a look at what the milestones are and where you are.

Ages & Stages

Developmental Milestones: 3 Months

What are some of the developmental milestones my child should reach by three months of age?

By the time your baby is three months of age, she will have made a dramatic transformation from a totally dependent newborn to an active and responsive infant. She’ll lose many of her newborn reflexes while acquiring more voluntary control of her body. You’ll find her spending hours inspecting her hands and watching their movements.
Here are some other milestones to look for.

Movement Milestones

Raises head and chest when lying on stomach (First day of life)

Supports upper body with arms when lying on stomach (yep you do this. You don't like it though)

Stretches legs out and kicks when lying on stomach or back (First couple days of life)
Opens and shuts hands (By third or fourth day.)
Pushes down on legs when feet are placed on a firm surface (3rd or 4th day)
Brings hand to mouth (First day)
Takes swipes at dangling objects with hands (hmm, you take swipes at your mom and me. I guess that counts.)
Grasps and shakes hand toys (eh... kind of, but not quite. No biggie, climbing holds are what really matters. ;) )

Visual and Hearing Milestones

Watches faces intently (First days of life. Before one week)
Follows moving objects (Oh yes, you do this. And you do it with a crazy look on your face as I make noises.)
Recognizes familiar objects and people at a distance (Yeah, I think you recognize people. You look at me like, "Oh boy, it's the play guy. What game are we going to play now? Oh, the zombie game again... )
Starts using hands and eyes in coordination (You are definitely getting smoother with your hand motions and making purposeful movements.)
Smiles at the sound of your voice (You smile at my nom nom nom voice. And you laugh at your mom's voice. Usually when she is trying to be serious. lol )
Begins to babble (You babble a little. You also laugh a little. Not too strongly though. Mostly you giggle a little. Your sis Brooke used to put herself into fits. so that is what I am basing it on. but you are a very happy baby.)
Begins to imitate some sounds
Turns head toward direction of sound (well, it is really hard for you to look over. You don't seem to care about things on the periphery.)

Social and Emotional Milestones

Begins to develop a social smile (hmm. not sure, your smile is more one on one play)
Enjoys playing with other people and may cry when playing stops (Ah, you are just starting this. Your grandma thinks you are sick all the time and your mom wonders why you hate her. LOL but once we move you around, you begin to smile.)
Becomes more communicative and expressive with face and body (true, as above.)
Imitates some movements and facial expressions (Maybe smile but nothing more yet.)

Developmental Health Watch

Although each baby develops in her own individual way and at her own rate, failure to reach certain milestones may signal medical or developmental problems requiring special attention. If you notice any of the following warning signs in your infant at this age, discuss them with your pediatrician.

Doesn’t seem to respond to loud sounds
Doesn’t notice her hands by two months
Doesn’t smile at the sound of your voice by two months
Doesn’t follow moving objects with her eyes by two to three months
Doesn’t grasp and hold objects by three months
Doesn’t smile at people by three months
Cannot support her head well at three months
Doesn’t reach for and grasp toys by three to four months
Doesn’t babble by three to four months
Doesn’t bring objects to her mouth by four months
Begins babbling, but doesn’t try to imitate any of your sounds by four months
Doesn’t push down with her legs when her feet are placed on a firm surface by four months
Has trouble moving one or both eyes in all directions
Crosses her eyes most of the time (Occasional crossing of the eyes is normal in these first months.)
Doesn’t pay attention to new faces, or seems very frightened by new faces or surroundings (hmm... You don't seem to pay a lot of attention to new faces... But, you don't see many either.)
Still has the tonic neck reflex at four to five months
