Congrats on baby on the way! I have 3 also. Some good advice I got is that "special" time doesn't have to be anything fancy at all. Special outings are done together - we only have the weekend to do them, and it would not be fair to take one kid to the zoo and the other not or something for example. But little one on ones are good to do every day even if it is only 5 minutes or 10 minutes at a time. Some things we will do:
1. I will walk the dogs with one child while the other is home with daddy.
2. Just sitting on their bed in their room and talking.
3. Reading stories together.
4. Painting or coloring together.
5. Snuggling
6. Cooking something together
7. Even something as simple as taking one food shopping while the other stayed home with dad.
