I havent read all the pp but I wanted to say yes it can be hard but its not all bad, its beautiful most of the time. The excitement on their faces when they first meet their new sibling, the great joy they get from cuddles... even now dd3 is 3 months old both dd1 and 2 are so happy to have cuddles and help feed and change their sister... its so special to watch. At the beginning when we were sleep deprived and grumpy they solidiered on they did much better than us. It was really me who regressed....
We also did gifts... dds1 and 2 got dd3 a dolly and dd3 got them gift bags each to play with at the hospital and take home to nannas house while they stayed there for a few nights. They loved it and still talk about it.

All the best x o
