To raise an only child, or to not raise an only child.. that is the question

My daughter has been saying for over a year that she really wants a baby brother or sister. she is 5 and a half.I really dont feel like I need to have another one, but can't deny that it would be a little nice.I've been debating this in my head for a long, long time. no clear answer comes to mind.Do I bring a life into this world just because my daughter wants a sibling? She doesn't even fully understand the complete ramifications of that.. though it's been explained that there wont be as much one on one time.every time we see a baby or even a toddler, she stops and talks to them and or finds a way to make them smile. there is not doubt she'd be a great big sister and a big help to mom.I can't wait much longer- in my early 30's now.feel like it's now or never.what say you fine folk? did any of you have a second child and then regret the decision? should another sweet innocent angle be brought into this world just because it would "be nice" and my daughter really wants me to?my husband says he is happy either way. so it's all in my hands. and i have no idea what to do.any advice guys? what is your stand on only child vs multiple children?please give any honest thoughts i really need some help with this. via /r/Parenting http://ift.tt/2sxn3ta
