My one year baby girl fell down from bed yesterday morning and hit her head back.She cried for two mins but when I took her out and consoled she became normal and played also.Then she took her nap ,had lunch and played too.she was fine the whole day..She slept in the night from 10 to 2.then she woke up I gave her milk.she slept and immediately woke up at 3 and started crying.she is not able to sleep even if she is getting sleep.one side she is teething and the other side this head hit.Iam not able to understand why she is not sleeping since 3..it is 6 in the morning now but she hasn't slept since these 3 hours.Iam actually worried and scared.Please help me...
