It definately gets easier to look after them although they take a bit more watching. My baby was happier once she could do things for herself. Sitting up, rolling over, grabbing feet etc. Everyone said that it would be murder once she could walk but I disagree. The look of acheivement on her face was great and she thrives on her independance.
Also as they start sleeping better you are getting a better sleep and that can only be a good thing.
Enjoy!
