Postponing Hajj due to Taking Care of one's Child

Q: My wife wants to perform Hajj with me leaving my son behind by some friends. She is still feeding the child. I am worried and do not want to leave the child behind as he is very sensitive and afraid of foriegn people. He wakes up at night and wants his mother all the time. I am trying to convience my wife to leave the hajj this year. Am I commiting a sin ? Am I obliged to take her with me for hajj?

Woman Bleeding Whilst Fasting

Q: I had a period of 7 days. I was bleeding on my 7th day but bleeding stopped by sehri of the 8th day. I took ghusal and started fasting but during the day, I bled little bit. I performed wudhu, cleaned my private place, kept roza, and read namaaz. Please explain to me if my roza broke or not? Do I have to take a shower again?
