I have 4 children. dd1 8, dd2 5, dd3 2 (nearly 3) and ds1 6 months.
My middle child is exactly like containher middle child. Dd2 is so laid back, easy going, perfectly behaved yet very confident. On occassions other people have watched her for me (like her friends mums or dd1 friends mums) and they have all commented on her lovely laid back nature. I know I am only slightly biased but she is just an absolute little sweet heart. A complete people pleaser.
Whereas, dd1 is challenging and as someone else on this thread said, erm interesting. She can be the kindest child to her siblings and friends but at other times very, very strong willed.
Dd3 is just the most mischevious wee thing we have ever come across. The other two girls will take a telling, or know when not to cross the line. Whereas dd3 will just go and do what she wants to do but quietly under the radar. She has no fear of anything or anyone. She is soooo naughty. She does things that the other two wouldn't even think of doing. Though, she melts all our hearts with her angelic looks.
My middle child is not a typical middle child at all. I have friends who are mums of three and all have the middle child who is hard work etc.
My fourth child so far seems even more laid back than my middle one. He doesn't sleep well but during the day is easily entertained etc. and just a totally smiley baby.
I don't think all middle children have the middle child syndrome. Can I also say i am a middle child so maybe just sticking up for all us forgotton ones
