Ness cheer up hun, your baby will be fine They are very protected in there and would have to be a pretty forceful knock if it was to harm him/her. Try not to worry, i know its hard. When i was pg with ds i was working in childcare and we had a violent child who would kick and punch me in the tummy, telling me he would hurt my baby, i was very scared that ds would be hurt and was part of the reason i ended up leaving work early, but ds was and is fine and a healthy 6 month old. Hope that helps to reassure you. But as the others say if your concerned give your hospital a call just to be safe
