A lot of newborn photos are taken with your baby in just their nappy or naked (although they may be swaddled or wrapped).  Multiple outfit changes can be tricky as most babies don’t tend to like getting changed and so it is hard to do it whilst keeping them asleep so I don’t recommend bringing along a lot of clothing changes.  If you have an outfit that you’d like your baby to be photographed in, then I would suggest bringing them along already in it so we can get that done at the start of the session without having to change them.  It’s really helpful to me if you don’t bring them with lots of layers on as that just means I have to strip them off again and potentially disturb them so I’d suggest one layer and use blankets to keep them warm and toasty on their journey over.
