OP I have 3 boys. Our 3rd baby was a total surprise as we were done at 2 kids but we all adore him. However other peoples attitudes were nothing short of disgusting in some cases (particularly DH family who only really value girls and actively favour them which dh despises). My own family were delighted. The reality is my 3 boys are very close.All very different natured though but that would be true if you had girls too I imagine.
The oldest (age 11) is strong willed and head strong and confident. He loves Lego, history, music and building. He does well at school and has a nice small group of friends (girls and boys) but likes his own space and time. He behaves generally well now but did cause us some issues when he was younger behaviour wise.
The middle one age 6 loves arts, crafts, playdough, learning, pink, soft toys and clothes. He is very popular and has lots of friends. He excels in school and often come homes with awards. He is well behaved. Last week him and his friend got chased and hit by a bunch of little girls in school. A few weeks before that a little girl slapped him and a few other boys repeatedly at soft play in the face. Girls have the capability to hit the same as boys if nobody teaches them that hitting is unacceptable.
The youngest is 3.5 years old and has similar interests to the 6 year old. He is still in nursery and they say he is doing very well and sociable. He also behaves well.
The younger 2 are very close and kiss and hug each other every day when they see each other at school at lunchtime. The oldest class goes into the school nursery once a week to read to the little ones. He choses to read to his little brother.
Life is busy but that's because I have 3 kids regardless of the sex of the children it would be busy. I get constant hugs, kisses and told I love you mummy loads. From what I have seen of boys who are "only son's tills they take a wife" it's often because there mother has chosen to favour there daughters over there son's so there relationship with there sons suffer massively due to this. Focus on having a healthy and loving relationship with your sons and ignore others nasty comments. My best friend has adult sons and daughters. She has a wonderful relationship with all them and they all adore her.
