It is a good idea to book sometime during your second trimester. As a newborn photographer, I only accept a limited number of sessions during a month so that I can give myself enough flexibility to book each session within 2 weeks of baby being born. So when you book it is not for a specific date - that way we can be flexible and we will be able to do your session in the right time frame. If you find yourself getting close to your due date and you haven't booked yet, or even if you have already had your baby please don't hesitate to contact me! I will do my very best to fit you in - newborn photo sessions really are my favourite, and I'll do just about anything to make it happen! Many newborn photographers will decline babies over 2 weeks. The reason is that many of the poses you see are easiest when babies are still in that very sleepy, flexible stage. Past 2 weeks certain poses are just more difficult, and sometimes not possible. However, there are still many adorable poses that can be done with an older baby. And once in a while an older baby will do just fine in just about all of the poses. Having said all of that, if you have the choice - please book your newborn session in advance - it really is best if we can do the session within those first 2 weeks.
