It gets better when they learn how to crawl. DD4 used to roll over to stuff when she was 2-3 months. She would stiffen her back and look for her toy and then roll over until she got there. Right before they learned to crawl was pretty rough with the girls.
DD8m would get frustrated and lunge at the other two as they went by. She would try to crawl and fall on her nose. Then one day she didn't fall forward and she was off. She also scooted for awhile before she crawled, mostly backwards.
Now she is trying to walk. She will let go of her wall or chair and lunge towards her sibs when they go by. If she falls she gets really mad and throws a fit, kicking her feet and yelling. Then she sits up and crawls as fast as she can to catch up. As soon as she gets her balance down shes going to be a much happier baby. She really wants to keep up with her sibs.
One thing I did with DD4 was I would play CDs or audio books with people talking or singing so I could put her in her crib if I had to do something where I could not hold her right then. She was a pretty happy baby but needed constant interaction. She still is like that. It is very helpful to spread out the love. Let Grandma or Aunts, friends have some turns. They also liked tv from a very young age and they liked computer games. It is easier now because they play with each other. DD4 will read sibs books while I do chores sometimes and DD2 likes to show the baby different toys and things he finds.
Your baby sound wonderful. Give your baby lots of snuggles they grow up too quick.
