We have a 2 year gap between our only two.
Yes it's hard, both parents full time at home for a bit, it was more of a shock to H than me as I was already full time child.
Less sleep than with first because when baby naps in day then toddler wants full undiluted attention, this is assuming a smaller age gap
But it was the best thing we ever did, we always said teo. They used to play, now talking about school, they kept each other company on holidays, they gave different strengths and weaknesses and it rubs off on both.
They love each other more than they love us which is how it should be.
Watching their relationship grow, continue to grow has been a total pleasure.
It has made pampered one more balanced with sharing.
And they will have each other when we die, all going well, who else will they recall family holidays with?
Not a single regret about second
Would never have a third it's expensive enough.
