Fetal Development – Know Everything About Your Baby’s Arms, Legs, Fingers and Toes By Dr. Prerna Jhawar

• It is around the time of 5 to 6 weeks when the baby sprouts two flipper-like buds, which will later grow and form arms.
• At around 7 weeks’ time, another two buds form and stretch out into the legs. At this stage, the arms and legs will look like paddles, forming at the end of the buds.
• During the 9-week mark, the spaces for knee joints and elbow will appear as the buds lengthen out.
• The fetal limbs will start to look less like flippers at 11 weeks when the baby can bend the legs and arms. At this time, the buds will start to grow even more, and the hands will close closer and meet over the heart. During this time, the fetal limbs will start growing muscles, bones, and nerves as well.
• You can see nerves’ presence at around 7 weeks, and the nerves will control the developing muscles by 10 weeks’ time.
• At the 10-week mark, the bone-producing cells start to develop to form the leg and arm bones. These bones will continue to grow, even after giving birth.

When Can You Experience Your First Fetal Movement?

Experiencing baby movements is one of the most precious and memorable parts of your pregnancy. As a would-be mother, you will surely be curious to know where you can experience your baby moving. Here is a breakup of the timeline.

• At first, twitching and stretching will happen spontaneously, and it will start around 7 to 8 weeks. You can see those movements when you are out for the ultrasound. But most women won’t be able to feel these movements during this stage.
• The baby will become livelier at 12 weeks of pregnancy. During this stage, babies can close and unfold their hands, as well as curl their toes. They will also start to move their legs and arms during this stage.
• When you reach 16 weeks of pregnancy, the baby will start to move and flex fetal limbs in a coordinated manner because the nervous system starts to develop at this stage. During this time, you can feel your baby’s movements. Some women might have to wait for a few weeks extra to feel the movements.
• Women with an anterior placenta or plus-size women might take some longer time to feel the kicks. So, there is nothing to worry about!
• Some women can place their hands on the stomach and can feel the baby’s movements. But for that, you have to wait till you can feel the baby moving inside your stomach!
• When you reach 30 weeks of your pregnancy, the babies will spend their time mostly sleeping. So, you will feel fewer movements during this time. However, the babies will sleep for a shorter span of time, like 20 to 40 minutes. So, there shouldn’t be a significant slowdown!

Once you become accustomed to your baby’s movements, you will be able to spot some of the major patterns. Some babies are highly active during the afternoons and evenings. So, you can feel their presence more during such instances. Then you have other babies who are hyperactive during morning hours. For parents, it is exciting to observe if the babies are following the same pattern once they are born. Some might follow the same routines, but most of them don’t.
