A newborn baby shoot at home often takes up to 2-3 hours giving lots of time for feeds and changes. Babies photograph well after a long feed, they become sleepy and 'milk drunk', so sessions can take a long time. Older siblings are welcome to join the shoot. It is often best for them to be included at the start of the shoot or to join towards the end. Young children often just manage 10-15 minutes (with all the attention on the newborn it can be hard!) so having a parent or friend to take them home can be helpful. 
I do not charge a session fee if I photographed your wedding, please call me on 0117 9094503 to book.
