Research process and flow Families who are willing to participate in the study will be provided with a diary sheet that will allow them to record over a baseline 2 week period how frequently their child stood and in what position. The diary sheet will be available in word or hard copy format. An e mail/ stamped addressed envelope will be provided to return the diary at the end of 2 weeks. Participants will be reminded via text/ phone / e mail (depending on their preferred method of communication) after 1 week if they have not returned their diary sheets.
