Some more ideas...
1.Sit next to your SIL when he's holding the baby, and try to connect with them. Talk to your SIL and or grandbaby, and be there to enjoy together when the baby smiles or gurgles, and to hold the baby if your SIL needs to go to the bathroom.
2. Get your SIl a plate (dinner) if he is holding the baby, ask him what he would like, bring him a drink, just let him know you like him :)
