I had a similar problem with my DS and DD when DS was little. I hated DD sitting in front of the tv, but sometimes needed that extra time to be with DS. I got a sling and wore DS alot in the early months, and also got an automatic baby swing thing which he would sleep in sometimes. Otherwise I would put him into the portacot in the lounge room and I could settle him while watching DD too. I would give her some crayons or she could play with the playdough at the kitchen counter and I could still see her. It's so tough to give them both your time when they are both so little! Good luck
