So everything's going swimmingly with child number one and you (think) you've adapted well enough to parenthood to have another baby.
But how do you know if you're ready?
The truth is, there are no hard and fast rules about when is the perfect time to have another child. There are pros and cons to small and large age gaps, so in that respect you'll be able to make it work no matter what.
However, having a baby has a huge impact on couples emotionally and financially. BabyCentre says that couples should ask themselves these five questions if they're thinking of getting pregnant again - to help them figure out if it's the right thing.
Is it the best time to have another baby?
Timing is everything. And having a newborn baby can completely take over everything - so it's worth considering what else is going on in your lives before having another.
Do you have the time and energy to look after a baby? And where are you both at in your careers?
It's also important to ask yourselves whether your other children are ready to deal with the realities of a baby at home.
In terms of age gaps it really is a matter of preference - some mums prefer large age gaps so each child gets plenty of attention, while others prefer smaller gaps so their kids have playmates.
Whatever you decide, make sure you consider your own health. Your body needs time to recover between births - so if you've recently had a baby, enjoy a well-earned rest before conceiving again!
How will another child affect you financually?
Having some degree of financial stability is essential for any family. Doubtless you know all too well that having a child can costs thousands more per year, so you'll absolutely need to keep some extra money aside.
Understandably, lots of parents find it difficult to keep up work once they've had kids - so think about what you're likely to want to do and how much nursery and childcare will cost.
Do you and your partner both agree?
Ideally, you and your partner will both want another baby at the same time. The reality is, this may not be the case - you may feel ready first or vice versa.
The most important thing is to keep the lines of communication open - it may be the case that your partner only just feels you have time for each other again, or doesn't want to miss a moment of those precious years as your firstborn grows up.
Either way, you may not resolve anything immediately. But you do need to understand each other's perspectives. If you are both ready, then there's no time like the present.
Will your age affect getting pregnant again?
Unfortunately for women, the clock can count against you if you want to conceive again.
For example, if you're approaching 40 and want two more kids spaced three years apart - time may not be a luxury you can count on as conception becomes more difficult with age.
However, there are no strict rules. Research shows fertility rates drop for women from their mid-30s onwards, but many women still conceive in their 40s.
Are you emotionally ready?
Most importantly, you should consider the emotional health of you and your partner. As you well know, a baby can cause dramatic upheaval and a shifting of priorities in your life - which is not to be underestimated.
Of course, having another baby will always feel daunting but if the prospect scares you in a way it didn't last time then maybe the timing isn't right just yet.
