Here's what is going on with Noah this week according to babycenter.com;
At last, your baby's sleep patterns may start to settle down, giving you some rest. Many 4-month-olds sleep for a six-hour stretch through the night, though others still wake for an occasional feeding. Some babies take until age 6 months or later to sleep through the night, though, so don't get your hopes up! Two daytime naps are usual now.
Your baby's starting to draw conclusions about the world around him. He's looking at everything with curiosity, even his own reflection. Prop an unbreakable mirror next to him or sit him in front of your mirror when you're getting ready. Your baby won't realize that it's actually his image in the mirror (this usually begins to happen well into the second year), but that doesn't matter. He'll love to stare at his — or anyone else's — reflection, and he may show his delight by an all-out gum grin.
Your baby may stop sucking his thumb or bottle to listen to your voice. By cooing or making noises at him, and by describing even the most mundane household chore, you're not only connecting with him but also encouraging him to express himself. Wait and see if he "answers." Your baby is becoming more animated and engaging (even with others) — flashing smiles, oohing, and cooing. And the fun has really begun as he's starting to laugh. When you're with friends, keep your baby nearby so he can hear the richness of human interaction. He'll enjoy watching the antics of other babies, toddlers, and pets, but keep up your guard: Neither he nor they know the rules of safe engagement just yet.
Anything within your baby's reach is fair game now. While he's mastering his grabbing skills, give your baby interesting things to hold: lightweight rattles that are easy to grasp, a plastic or rubber ring to hold with both hands, squeaking toys, or soft stuffed animals. Your baby will start to favor one hand for a while and then switch to the other, but you can't really tell whether he's a lefty or a righty until he's about 2 or 3 years old.
Noah is doing great! He seems to be getting thinner, but we don't think he's losing weight he just seems to be growing longer right now. This week I packed up some of his 3 month outfits that don't fit anymore and dug out his 6 month clothes which he is wearing now. For several weeks Noah has loved staring in mirrors and gives huge grins when we let him do that. I tend to read him a book (or more a day) and I think he likes staring at the pictures. He can now hold his head up at a 90 degree angle when he is lying on his belly. He loves kicking at things with his legs, whether he is pushing off of us, or I like to put him in his crib, close to the end and let him kick and push away. He is also really starting to enjoy his mat with toys dangling down at him, he doesn't only bat at them now, but reaches and grasps for them a lot. He loves going for walks, in the stroller or Baby Bjorn carrier. His eyes are still very blue, and we're hoping that they are not going to change colors. As of now we think he's a pretty good combination of the two of us... my mouth, chin, hairline and profile, Jeremy's eyes and maybe nose. I also tend to think that he has a lot of his daddy's personality... which is fine by me... I'm a pretty big fan of him!
