MUCH NEEDED BIRTH ADVICE ??? Irish twins !

So my kids are 11 months apart maybe less I’m not sure because I’m currently pregnant with my second child and my first is 10 months now .

What I need advice on is basically

Are there any mothers that have Irish twins ?

Or kids at-least 1.5 years apart

I need to know :

will my second come sooner?

I carried my first until 41 weeks

Will my delivery be more painful?

I had my first natural and had a small laceration

Labor was quick with my first

Will my labor be even quicker or longer ?

There’s not much information for second time mothers so please comment your experience having two kids close in age !!
