Hi sp9arkles, my second baby arrived when my eldest had just turned 2. I won't pretend it was easy, but I must share a brilliant tip that an old neighbour/midwife gave me at the time and proved invaluable.
She suggested having a 'morning box' and an 'afternoon box'. It was simply a box full of snacks, drink, puzzles, toys - in fact anything your toddler may ask you to retrieve whilst you are feeding or dealing with the new baby. I would exchange a few items every evening and my daughter would wake excitedly asking for her 'morning box'. This would keep her busy for at least the time it took to feed my little one.
Good advice from Evada too - all the best, and enjoy this precious time - they grow up far too quickly!
