We also had two in quick succession due to our age and I've found it really hard. I can identify with some of the point here - constant mum guilt at splitting your time and attention mainly.
I am in the process of trying out slings as this would help massively, my main problem is not enough hands currently! We've also found a good play centre which is small enough that DC1 can go off and play while I sit with DC2 to feed. I found out on my own at a bigger play centre that this is crucial when the bigger one is still too small to go on everything and climb the bigger bits alone!
I've found the transition much harder than going from 0 - 1 and opened this thread fully expecting others to feel the same. I'm surprised that I'm in the minority but maybe everyone else has their shit together and I haven't 😆
My second is almost four months and I can see (hope?!) that it may become a little easier when they can sit unaided or will be put down for five minutes, maybe this is just wishful thinking??
Thinking about it I find it easier when I am organised and we are out the house. Yes is is physically more demanding with a pram for two to lump in and out the car and a toddler to ensure doesn't dart off across the car park while getting the baby out of the car, but while writing this post I've realised that I've got this.
I spend my time looking forward to them being older as I imagine it's easier, but as I know from DC1, it doesn't get easier, just different.
Another mum recently told me, when they are little it is physically hard, as they grow it becomes mentally harder. Well I think this is what she said, we struggled to have a conversation over her two older ones chatting and constantly asking questions, making observations, providing a running commentary on dinner....!
I will miss them both being little and I should enjoy it as DC1 becomes more and more loving and protective of DC2 and DC2 is beginning to recognise and react (positively!) to DC1. In fact, it's bloody hard, but I would't change it for the world!
