There is 2 yrs 3 months between DD1 and DD2.
I didnt find it difficult to begin with,expected it to be awkward at times such as feeding etc.but DD1 accepted I was "busy" and was content to watch T.V.
But i think DD1 was particularly good,have friends that had DC1 climbing all over them or having a tantrum when breastfeeding/F.F.
"They" usually advise putting together a bag of "new" toys/books etc.that you only get out at feed times,and be prepared to be an "octupus" at times,ie. reading to DC1 whilst feeding,putting toys together etc.
It does help if you can try extra hard not to make DC1 wait for your time,as IME this causes more frustration and possibly resentment later.
There is plenty of time later for them to learn about waiting their turn etc.
As for buggies, my DD1 was a little afraid of the Buggy Board until she was 2.5 yrs + So we used a Double buggy initially,then the Buggy Board when she was happy.
It is lovely to have them close together,initially you are very busy,but later they have a playmate which leaves you free.
