48th week your baby is very near to his/her first birthday. Time really flies too fast. Last year at this stage, you didn’t even think of this big moment. One year has passed so quickly and your baby is getting more active, energetic and strong. Throughout the development of baby, it is perhaps a big occasion for you than your baby. He/she is too young to understand the concept of time and may not be able to understand it for another couple of years.
This week your baby may or may not be walking yet, but he(she)'s certainly trying to get around. He/she cruises on furniture, holds your hands while taking steps, and may not even want to sit down. This is a major milestone, though babies may take that first unassisted step at anywhere from 8 to 15 months. You can help him/her walking skills be giving his/her a sturdy push-pull toy, and placing furniture in strategic areas to encourage his/her cruising.
At 48th week old, babies usually range from 27.25 inches long and 17.5 pounds (10th percentile) to 30.25 inches long and 23 pounds (90th percentile). Your baby's appetite will go through many changes and about this time it might drop, even while his/her interest in food increases. Babies usually triple their birth weight by their first birthday, but only gain a few pounds between the first and second. Don't worry about your baby not eating enough, he/she will eat all he/she needs, and will learn to stop when he/she is full.
