A lot more development is yet to come all throughout your little one, both externally and internally, as he or she builds the strength and size needed for when they arrive in the outside world. The next twenty eight weeks are known as the maintenance phase, where organs continue to perform gentle work, for example the fetal digestive system has started to contract and gently flex its muscles, in preparation for your baby to digest milk in twenty eight weeks.
Your baby even has layer of fine hairs all over their body now, and they will start to wiggle their fingers and toes and wriggle around more now they have more developed muscles. Your baby’s reflex to touch will have developed and your baby may move in response to your hand on your tummy, although your little one is still too small for you to be able to feel this yet!

At week twelve of pregnancy you will probably have the beginnings of a visible baby bump rather than just feeling bloated. If you haven’t told people your pregnancy news already then you may wish to now. Your mood swings should begin to settle and your pregnancy feel more real to you now that you have a baby bump and if you feel more relaxed to tell people.
If you have any symptoms that concern you it is important to consult your doctor as soon as you can.
