Congratulations on your new arrival!
I'm 2 months in with a 21 month age gap and it's already got easier although the witching hours have now started with the baby making dinner time pretty horrific with a screaming baby and a tired and hungry toddler!
My tips so far... Get the toddler to help with the baby, fetching nappies etc and get them used to doing things for themselves or at least trying to with your help (getting dressed, putting their shoes and toys away etc).
Prepare dinner during the day as 5pm is horrific otherwise. On a bad day it won't kill you all to have bread, cheese and fruit or porridge for dinner!
Get out the house as soon as you can, otherwise you get dragged into the downward spiral of nappies, feeding, settling baby to sleep.
Accept that there will be times where one or both of them has to be left to cry for a few minutes because you only have one pair of hands.
I put the baby in the sling at breakfast and dinner time and she will generally sleep for a couple of hours while I feed us all, tidy up and play with the toddler.
As for bedtime, DH is fortunately usually home in time but I get the babysitter in to put the toddler to bed when he's working away. First the cluster feeding baby made it impossible otherwise and now the witching hours have started. If I try on my own it usually ends up with two screaming kids.
BTW how was the birth? We were often on the same VBAC threads from recollection!
