DD2 was 16 months old when DD1 (2 and a half at the time) jumped off the couch and landed on her arm! I wanted to take her to the local Dr because I thought it was broken or badly hurt. DP was convinced she was fine cos she was playing and stuff as usual. It took me 4 days of asking him to take us to the dr before he gave in saying he thinks it's fine just bruised. Dr looked said there might be a slight fracture it was broken the dr and DP were shocked cos she had been playing and not complaining. I may have said I told you so lol. Definitely take her, just to be sure
