21m dd and 2 week old baby. since coming home toddler has gone between being very loving to very nasty with her. she will come over and ask to kiss baby, so i let her kiss the top of her head, asks for a hug from her etc etc. most of the time she will leave it at that and walk away, but sometimes she will do the hug/kiss/etc business and then suddenly claw at her face. it happens so fast i can’t stop or predict it. today she has done it about 8 times so i’m having to just say no you can’t come near baby which i feel will just make her more jealous and more likely to want to hit her. she also keeps throwing things at her like toys and books.
any advice please? i know it’s still all very new for her but starting to get embarrassing and upsetting having a newborn who has scratches etc down her face.
