I don't see how you can find out. Unfortunately it is quite common for small children and/or babies to be attacked in this way; usually by other children, although there are quite a few wicked adults about! Just try to make sure that your baby is never left alone. Don't leave a baby outside when you are in a shop. Take the baby inside with you.
Try talking to some people. If you leave your child at a day care see if they do back round checks and if they do ask to see them. Also use your intuition if you sense something about somebody that's not right do some more research on the internet about these people. Ask your child if someone is bullying her and ask for his/her name. Then talk to the parents and make sure you have contact with anyone who regularly sees your child everyday like babysitters,friends,relatives,coworkers, the other parent, and especially the other kids. If your child says it happened again she probably isn't lying because toddlers tend to be pretty distracted at that age. So if you think an adult is abusing your child go to the police, alright hope this helps.
Oh this person is an adult and my baby is 13 months and I was by some one who I trusted. But lets just say their is NO TRUST NOW. I did not know if there is a dream spell I can use to see what she did to my ANGEL.
I like babies fine (I have one of my own) but it's true that you can't always assume they're telling the truth. They will often make up stories to get their way. Even good kids do this. It's a stage of human development and doesn't reflect on their general honesty once they've grown.
If your baby isn't hurt, and you trust the person in question I would not abandon that trust on your baby's word alone. If you have other reasons to believe that it might be true, then watch closely. You can always ask the person in question and watch for signs that they feel guilty.
There is no magical way that I know of to figure out what happened. If your child is ok, I'd assume it wasn't too bad anyway. Babies have sensitive skin and sometimes they think they've been grabbed or slapped when they've only been touched roughly. If there was some genuine abuse going on, there would have been a red mark or bruise on her face. Babies bruise easily.
I sympathize with you and I hope you do find out what's going on. You might have to accept that it's one of those things that might never become clear.
See the person was famliy. And asked her to watch her in the car while I ran in to the shopping center to let my mother know we was in the car and my mum asked me to cash out while she went out with my baby. When she got to the car my baby was crying so hard with tears and my cousin did not take her out of the car seat or get in the back seat with her. And my daughter is not the type to cry like that. And my mum went to wipe her tears and she flinched and then l8r that day my baby said she did this and grabed her face. So I dont know just shes not watching her I dont want to take any chances u know.
