around 45 mins ago my seven month old was trying to put herself up on the corner of the sofa she got about halfway and then slept and banged her head. shes been crying on and off since then although has stopped when ive distracted him with things he finds funny. Can't work out if it's related or not as it was also close to nap time. He has a £2 coin size red mark where he banged it. Should I take him to a+e. Help please.
