Sibling rivalry unfolding

Episode 1 - Baby Aditi, now 6 months was bawling a few days back. Tried to divert her attention and gave her Anish's basket ball (newly gifted by Papa). Immediately Anish plucked it away saying "she's too small to handle such a big ball. Let her grow up and I will give it to her myself" Uh oh!

Episode 2 - For his 8th year birthday on 11th October, Big Boy got a Scrabble board from his school principal and was showing it off at home. I gave an alphabet piece to Small Baby just like that (dumb parent you might say now) and immediately Big Boy snatched it away with a warning "Mummy you dare give her my stuff! If anything happens (as in if Small Baby spoils it), I will spill all her milk!"
