Hi, I know you did this post a while ago but I tend to use a book called - 'From Birth to Five Years - Children's Developmental Progress' by Mary D. Sheridan. I bought my copy on Amazon for £7.99 ISBN 0-415-16458-3. It is a small book that covers topics at different ages on: Posture and large movements, Vision and fine movements, Hearing and Speech, Social behaviour and play; at ages: Newborn, 1, 3, 6, 9, 12, 15 & 18 months, 2, 2.5, 3, 4 & 5 years. It also includes illustrations and more detail on Patterns of Development in section 2. All in all a good buy for checking that a child is on the right path in their milestones.
