Your baby has ears! Low down, near the jaw line, the ears form, each arising from six small mounds, fusing together to give your baby his unique and individual ear shape. As the face and jaw forms and your baby's neck extends moving away from the chest wall, the ears migrate upward; they will come to lie at the same level as his eyes by 11 weeks.
The lips and nose are now beginning to take shape. To form the upper lip, two separate ridges of tissue grow from each side of your baby's face to fuse with the small piece of tissue in the midline extending downward beneath the nose (the grooved part of the upper lip).
At around this stage, your baby's small and large bowel lengthen. Because they have insufficient room to expand inside the still very curled-up embryo, the intestines appear as a bulge on the surface of the abdominal wall. This bulge is covered by a membrane, into which the umbilical cord becomes attached. The bowel will continue to grow in this embryonic sac until 11-12 weeks when it will be reabsorbed into the abdominal cavity, leaving just the surface attachment of the cord.

Secondly, there's a risk that food-borne illnesses can affect the health of your baby, so it pays to be cautious. Do the following:
