So I was getting baby boys bottle ready today and I wasn't really thinking and I started shaking the bottle up to get it ready the same time as I was holding him. It wasn't really rough or anything I just don't want my baby to be hurt! :,( does it take more than that to cause shaken baby syndrome ?!? He's not acting different but they say it can take up to a day! I'm a ftm, this might be a stupid question but I'm worried!!
