From the moment of conception to the final delivery, there are thousands of changes occuring in the development of a baby. While we all hopefully know how conception works, there are countless other details that we may be a little fuzzy on, such as when can we hear a baby’s heartbeat? Or what size is the baby at two months? When will parents find out the baby’s gender? Or when can expecting parents first have a 3D ultrasound done?

Many first-time parents have questions running through their mind every minute of the day, many of them relating to the size of the baby. If you are expecting a baby, here is a quick breakdown of how the baby is growing and developing each month of the pregnancy.

If you’re looking forward to getting a 3D or 4D ultrasound done so you can finally get an idea of what your baby will look like, we’ll let you know. And when you have a date marked on your calendar, make sure to schedule your appointment with Kicks & Giggles in Orem.
