Your baby at 12 weeks
Your baby is the size of a lime. This week your baby weighs 8.5-14 g (0.3 to 0.5 oz) and measures around 6.5 cm (2.5 inches).
Those little nail beds are sprouting nails, so stand by with some nail clippers. Many babies are actually born with long fingernails that need to be trimmed soon after delivery.
Parts in place
The truly critical period for your little one's development is coming to a close. By the end of this week, all of the body parts will be there; even the sex organs have developed (although it's too soon to determine whether you're carrying a girl or a boy).
At 12 weeks, the eyelids have formed and will close. They'll remain fused together until late in your second trimester.
Your pregnancy at 12 weeks
Lock away those take-away menus: the appetite is back! Around this week, many women report feeling that 'the baby is hungry'. Make sure that you're eating enough and maintaining a healthy diet, but don't feel that you actually need to 'eat for two'.
What's normal, what's not.
As your blood volume increases to keep your baby nourished, you may find that your gums are more sensitive and bleed when you brush or floss. While this can be disconcerting, it’s completely normal.
Did you know?
By the end of this week, all critical body parts and systems have formed. Your baby has also doubled in size during the last three weeks! While the sex organs have formed, it’s still too early to tell whether the baby is a girl or a boy. His or her face has also developed a human profile…who will baby look like??
Quick tip for moms:
As your morning sickness disappears, be sure to eat a balanced diet that includes meats, chicken and fish (protein), vegetables and fruits (vitamins and minerals) and dairy products (calcium) to help your child grow and develop. Don’t forget: that old wives tale that you need to “eat for two” does not mean eating twice as much!
