Your baby will double in size by the end of the week
You may not feel like you are pregnant yet but that doesn't mean that there isn't a lot happening! Even at this early stage your baby is developing rapidly and the neural tube is already forming.
Your baby's heart will soon start to beat
Already, your baby is receiving nutrition and oxygen through your placenta. This will continue to pass them nutrients from you and oxygen throughout the next 8 months.
Baby's lungs, liver and pancreas are all being formed
You may be feeling tired at the moment and it is no wonder with all that's going on inside you. Your body is getting used to lots of physical changes and your baby is growing rapidly.
Your baby's heart is beating twice as fast as yours
An adult's heart usually beats around 60 - 100 times per minute but your baby's is already beating 150 beats per minute - this will even increase further to 170 in a couple of weeks.
Your little future genius already has a functioning and rapidly growing brain!
Your baby's head will appear larger than their body as their brain grows rapidly now. When they are born, around 25% of their adult brain will already be formed. This will increase to about 80% by the time they are 3 years old.
Fingerprints are formed in the womb by your baby touching the environment around them
Your baby is reaching out and touching structures such as the cord and the uterus walls. The pressue of this on their tiny fingers will result in "friction ridges" which form fingerprints that last a lifetime!
Your baby now has their own unique fingerprints! Their neck is beginning to take shape, their body muscles are almost developed, the jaws are in place and nipples and hair follicles begin to grow. While it is still too small for you to feel baby is moving, wriggling and shifting and they are able to flex their wrists and elbows.
During your pregnancy, there are some foods and drinks you should avoid – even though many of them are good for us, they have the potential to cause problems for your baby in the womb. These foods include unpasteurised milk and cheese products, all soft cheeses, undercooked eggs or meat or pate. Familiarise yourself with these and other foods by having a read of our "foods to avoid" list. Food hygiene is also very important to reduce the risk of food poisoning which can be harmful to your developing baby.
Baby might be tasting different flavours depending on what you eat!
Your baby's taste buds are now formed and as they swallow mouthfuls of your amniotic fluid they may experience different flavours depending on what you eat.
Baby can now get hiccups and their vocal chords are complete
Although you can't hear them making any sounds as sound can't travel through your uterus they are practising using their vocal cords before they are even born. And once baby arrives you will see that they have been giving them a good workout!
Your baby will quadruple in weight during month 4
During the second trimester you need to increase your calorie requirements very slightly. You need about 350kcal extra per day and this can be easily reached with just 1-2 extra healthy snacks.
Baby is covered in a fine hair called lanugo
The fine hair that covers their body is to protect their skin which is still very transparent. Most babies will shed this hair before birth but some babies (particularly if they arrive early) may not shed it until after birth.
Baby can now make a fist
Their legs and arms have grown significantly in the last few weeks and their body is now longer than their head which developed more radidply to begin with.
