Do you encourage your children to tell each other "I Love You"? They need to know that their siblings love and value them not only to raise their self esteem but to avoid self pity assumptions that are not true.
Do you encourage your children to tell each other how great they are? Self esteem is one of those things that needs to be nurtured and what better way then by their siblings? Siblings who know that their sibling thinks they are a great sister or brother will strive to continue to keep that title. This also will ensure that wrong and damaging assumptions are not made.
Siblings will fight and they will get on each others nerves. They will say mean things to each other and hurt each others feelings. The result of which can be blown out of proportion if they are unsure if their sibling loves them. If they already believe that their sibling can't stand them more negative words will only prove their mistaken assumptions.
This is the month of love. Why not encourage more love in your home by establishing an "I Love You" habit. No one goes to bed without saying "I Love You" to everyone.
