In this study, we are looking at how caregivers and their babies interact. First, you will be asked to read a book with your baby. Please have a short book, that your baby is already familiar with, ready for this. Next, you will be asked just to play with your baby for a few minutes. These tasks will be recorded, so please plan a space down on the floor and position your laptop/webcam so that you can both be seen. Finally, we will ask you to complete a questionnaire about your body, your mood and your baby. At the end of the questionnaire, you will find a special certificate for your baby!
