20mo DS1 will be 2.3yrs when DC2 arrives in Feb. Still early days but I was lifting him into his cot earlier and though maybe I should think about tweaking things a bit before I get huge and grappling a toddler gets harder 
Other things have occurred to me too - DS doesn't watch tv ATM (not interested); should I introduce him to cBeebies now so as to buy myself some breastfeeding time later??
Is he too young for those nauseating 'Mommy's having a baby' books??
Advice gratefully received.
