Some things will depend on the personalities of your kids. My 8 yr old son adores his little sister so much he wants to marry her. He is much more tolerant of her than he was at 2 yrs old when his brother was born. Some of that comes from his added maturity, some is his personality, and some is just his relationship with her. Our routine changed completely when our 3rd was born, but that was fine because my boys had grown in their understanding of the concept that families make sacrifices to support one another. I liked that my boys were old enough to get themselves ready for bed or get their own breakfast if the baby needed me more than usual at those times. The 3rd baby got less attention from me than the first baby got for sure. But on the plus side she got lots of attention from her brothers to make up for it. One of the hardest parts was toting her around town when she did not want to be in the car. Or getting her up in the middle of a nap. If it was time for another family member to be somewhere, we didn't have the luxury of working around the baby's schedule. We just had to get in the car and go, letting her cry until I could give her the attention she wanted/needed. The boys worked hard at calming her in the car, but there have been plenty of times that my younger son got fed up and hit her or just broke down crying because he couldn't stand the noise. A few times I even had to nurse her only on one side, stop to get one of the boys to or from school or pick up their dad from work, then when we got home I would finish nursing her on the other side. You'll probably have a kindergartener when the baby is born, which typically means half day school. It's annoying to have to pack up the baby to take the kindergartener to and from school, but with some good planning, it can be done. Your routines will all change a bit, but there can be a lot of joy for the whole family in making room in your lives and hearts for a new little family member, no matter your ages. Good luck and God bless!
