I've got two sons who are now 22&24 so I've done the whole lot.
DS1 was the most laid back child on the planet. He'd lie in his prom/basket/chair taking it all in then fall asleep when he was ready. He didn't fuss at all. He'd sit for hours on our laps looking at books, he loved to colour, building with Duplo or Sticklebricks kept him amused for hours. Forget mud, puddles, paint or any of that jazz he was having none of it. He hated being dirty. He'd go to the edge of the sofa or bed, peer over, look at the drop decide it was too much so scoot back and go back to what he was doing. I felt like, and still do, the luckiest mum alive.
When I was pregnant with DS2 I was adamant I didn't want a girl because compared to DS1 my nieces were nightmares. Well along popped DS2. He soon proved to me that there's no such thing as "boys are like this and girls are like that" because he came out screaming and didn't really stop until he was almost 2. He was constantly stuck to me. I couldn't leave him with DH until he was over 12 months because he'd scream blue murder. Before he could walk he could climb. He was a magnet to mud and although he hated having his hair washed he loved washing it in puddles.
They've both always loved cuddles, even now. DS1 is a big, muscly soldier but he never ends a phone call without saying he loves me and he always wraps me up in a huge hug every time he leaves the house.
DS2 was my shadow for years. He's left home now but we talk every day. He's the most caring, loving person you could wish to meet and is incredibly sensitive. He loves his cuddles too and at 6'4 he's much taller than me so sometimes he gets on his knees so he can fit under my chin again.
I absolutely adore being a mum of boys. There's nothing negative about it.
Congratulations on your baby boy.
