Ever since my youngest was aware of her sister, could sit up crawl ect every time she touches her she just screams and pulls away. She will laugh at her if her sister is arms length away if shes making silly noises stupid faces etc but if she tries to hug or kiss her, carry her even just stroke her hand she will scream and shout until she let's go. It's really starting to affect the older ones confidence and she thinks her sister hates her. If I'm honest the baby isn't much of a people person and will whinge and try to get off anyone that's not me (sometimes even dad) but she screams to another level with her sister. Should I be worried about this? Is there anything I can do to help the situation? I try to find a common ground for the both of them but it's quite hard with a such big age gap
