[Info] Baby Week 23
To help build baby's leg and torso strength, gently pull him up from a sitting position and hold him while he stands for a few seconds.
Baby's starting to understand cause and effect,which means he loves grabbing, tasting, banging, shaking, and throwing. This makes it especially important to keep sharp objects, breakables, drinks, and your hair out of baby's reach. He's also learning to differentiate pastel colors. Keep exposing him to books and toys with wide ranges of hues to further expand his awareness of color.
Being on his own helps him get comfortable with independence. Lay a blanket and some toys on the floor, and let baby play by himself while you keep an eye on him. Watch for fussiness, and pick him up if he seems like he's going to cry -- remember, tears are still his only way to say "I'm bored."
