I was 20 years old when i had my first baby and 21 when i had him,and i freaked out aswell.Not only for looking after him but the birth too.Its all normal and it doesnt change or stop there. In my second pregnancy i felt the same,there was a big gap between my first pregnancy and my second.My son was 9 when my Daughter was born.But even now on my 3rd pregnancy im now thinking omg i will have 3 children too look after. Once they are here you wont believe how quickly you adapt and get into a routine.Not meaning to sound sexiest,but it comes more natural to woman when it comes to babies and children
