I'm sorry your feeling overwhelmed and guilty, we all do at times. I also have 4 and they are ALL GIRLS!!! My girls are 20, 11, 8, and 5. My oldest is now 3 hrs from home in college and I can barely have a conversation with her sometimes without the others interrupting and needing or wanting something. No matter how much I give they all seem to want more. My most needy by far is my 11yo. For the last few years she did allstar cheer. I was always taking her to and from practices, watching half the time due to a pretty nasty coach. We would go to away competitions all the time, just her and I. She had tons of alone time with me. Well this year she decided to go to dance. Her dance studio does not allow watching and it is a technique program so they don't compete, it's just 2 recitals a year. She is really struggling this year missing that alone time. To top it off her 8yo sister is now on the travel team for gymnastics and so she is getting that alone time that the 11yo is missing. When it was my 11yo needing me no one complained but now that it's the 8yo the 11yo is having pretty bad issues with jealousy. She also uses the guilt trip. I do date nights with her so that she still feels special but it never seems to be enough. I really just think it's her personality. I can't do any better than my best so that's what I do and I hope one day she understands.
