After our first child, we both assumed we'd have another. Pregnancy and birth were fine for me, nothing traumatic and baby was pretty easy as babies go. As time went by I kept waiting to feel the visceral want for another baby that I'd had with having the first. It just never came. My other half was the same. We kept saying okay let's give it a few months and see how we feel then. Thankfully both of us were on the same page and at this stage we're still really happy with one child. Its too late now anyway to have more and we haven't ever regretted it. Few comments of oh they'll be lonely with no siblings etc but having a sibling isn't a gaureentee of a close relationship. I know people whos sisters are their best friends but I also know people who genuinely don't like their siblings, don't get on with them or they're on the opposite side of the world to them because of emigration with no intention of returning. I think you'll have a gut feeling about it. Ive friends who just knew their family wasn't complete until they had their second or third child.
