It is somewhat flattened, considerably narrower than the gastric surface, and is in relation with the upper part of the anterior surface of the left kidney and occasionally with the left adrenal gland. Like the thymus, the spleen possesses only efferent lymphatic vessels. The spleen is part of the lymphatic system. Both the short gastric arteries and the splenic artery supply it with blood. The germinal centers are supplied by arterioles called penicilliary radicles.
It depends on how well your baby is sleeping at night. Some babies confuse their days and nights â sleeping more during the day than at night. One way to set your baby straight is to limit daytime naps â especially those in the late afternoon â to no more than three or four hours each. If your baby is napping for too long at the end of the day, it can make it harder for him or her to fall asleep at bedtime.
By 9-12 months old, your baby will need about 14 hours sleep each day. A typical child of this age will sleep about 11 to 12 hours at night with two naps during the day.Each nap will be about one to two hours long.You may find that by the time your baby is a year old, her morning nap is shorter â and she may give up that morning nap! Plan lunch for about noon with an afternoon nap at about 2:00 PM. 2  Most babies will need a snack after the nap. 3  Dinner should be with the family at your regular dinner time. 4  If you follow this schedule, your 9-12 month old will be ready for bed by 8:00 PM after a bath and snack.
