I absolutely love this stage when they go from these sleepy little bugs to people. First smiles, getting to know their personality, seeing the look on their face when the recognize you... it's absolute perfection!
We went to the pediatrician today and my little man is growing! He is now (at 5 weeks) 9 pounds and 20 inches. The doc said he is around the 25th percentile for both. So he is still on the smaller side but growing beautifully!
