Preparing 2 year old for new baby brother coming in 12 days?

My son just turned 2 a week before his little sister was born I had the same issue I gave him extra tlc and told him nothing would change except he would have a sissy and mommy loved him so much and he is suppose to look out for sissy and have to help with the baby which he loved doing he felt like a very big boy and I would reward him we still have one night a week that just me and Ethan go have a night out and spend some one on one time and I also do the same with Maggie they need to know they are loved and the baby is not going to take that away
