Do you think she might be copying Rylee?? I know Rianna copies both the big girls, and Dion depending on whom she thinks is getting more attention.. Maybe she is starting to realise Rylee screams, and gets held by mommy because of this.
Dunno. Maybe just put Rylee down in her bed for 5 mins whilst you put Kels to bed, read a little story, cuddle a special friend (even if Ry cries for a few minutes whilst Kels gets mummy all to herself??? ) that would be my take on the situation. After being sick, and in hospital, Kels is scared you will be with Ry all the time and never her??

Im sorry life is rotten ATM. Maybe with DH home for the day tomorrow will be better ( will "x" still be bugging you ??)
