Hi Sarah 
I have two children as well - Jacob who is 3 years old, and his little brother Benji who is going to be 2 years in September! There is only 18 months and 2 days between them age wise!!
Jacob is a right little chatter box and has as much energy as Sportacus x10 !! He is starting pre-school full time in September - which should be a godsend! Every morning he'll be off to school in his uniform! I am *so* going to cry on his first day !
Benji is just a pain in the bum LOL! He is into everything, but totally plays the 'baby' card and he gets away with a lot more than I let Jacob get away with at that age!
Benji is really lazy with his speech because Jacob talks for him! Drives me mad.. but hoping that will change once Jacob is at school - I am planning to ignore Benji until he says proper words to me!
He will say some things - for instance this week he started saying the word "boobies"
but "mummy" still evades him!!
He even said "Gand-ma" the other day to my mum - bloomin' child!
Anyone else find the second child does this?
Great idea for a thread by the way - I love my boys so much, and I wouldn't have them any other way. Since Benji started sitting up they have always played (and fought and shouted) together, it's fantastic to see 
I have recently started a new relationship - and although our children haven't met yet - it should be interesting when they do! We will have a 4 year old, two 3 year olds, and a 2 year old between us!! Mayhem!
Look forward to hearing from other mums soon too
