<s>[INST] my 19 month old is like any toddler happy and not a worry - however noticed yesterday when changing her for bed she had a small lump to the left of her belly button, size of a marble and it was a blue colour. This morning the lump is smaller and the colouring has spread to the size of a 20 cent piece and is now a bruise like colour. Wasn t sure whether this was good or bad. Thinking maybe she has just fallen over and hurt herself, and hence got this lump which is slowly clearing [/INST] Hi ! Good evening. I am Chat Doctor answering your query. Yes, this could have been caused by a trivial trauma, and now the hematoma started getting absorbed. However, if that did not clear in a weeks time, I would advise you to get it clinically assessed by your pediatrician/general surgeon in your area. I hope this information would help you in discussing with your family physician/treating doctor in further management of your babies problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. I wish you an early recovery. Chat Doctor. </s>
