Our baby is 7weeks old.One day we sow on our baby buttom these blue marks,we call to the hospital straightaway,they ask us to bring her to the hospital.These bruises a really large on both buttocks,we never harm our baby.After few hours me and my husband were arrested for child cruelty,now its been 4weeks and our baby is in foster care while they do investigation.Its heart breaking,we have no idea how these bruises emerged in the first place,could it be these birth marks that everyone is talking about?but she is white skin,we both from eastern europe.Police took her infant baby bath,cous we told them it my be cous of the bath.Any advise or anything that could help us please?we try to get help for her and look whats happend,i never imagen in a million years they can do this.thanks
