Into complex designs
At this point, your baby will begin to move beyond his early preferences for bright or two-toned objects toward more detailed and complicated designs, colors, and shapes. Show your baby — and let him touch — a wider variety of objects. Good choices include plastic cookie cutters, soft balls, and stuffed animals.
Hear ye, hear ye
Your baby can differentiate familiar voices from other sounds and is becoming a better listener. He also can show you that he's in tune with his environment. Notice how he looks to see where certain noises are coming from.
An ongoing conversation (although still one-sided!) can help your baby develop his sense of place. He may even watch your mouth as you talk, fascinated by how it all works.
Note: If you have any doubt about your baby's hearing, don't hesitate to mention your concerns to your healthcare provider. Even though your baby's hearing may have already been tested, new problems can arise.
A helping hand
The chaotic first months are over and your baby's schedule is probably becoming more predictable. If you and your partner are raising your baby, it's important for both of you to get a chance to care for and bond with your baby. Make sure whichever one of you is not the primary caretaker gets regular time alone with your little one, for bathing him, changing him, and just getting tuned into his needs.
If you're a single parent, try to find another adult, such as a grandparent or an aunt, to spend time with your baby. This will give your child an opportunity to bond with other loving adults, and give you a welcome break from the hard work of being a parent to a young child.
Remember, your baby is an individual
All babies are unique and meet milestones at their own pace. Developmental guidelines simply show what your baby has the potential to accomplish — if not right now, then soon. If your baby was premature, keep in mind that kids born early usually need a bit more time to meet their milestones. If you have any questions at all about your baby's development, ask your healthcare provider.
