What should be the age gap between two kids

There is no one-size-fits-all or even -most answer. It depends on what type of personality the parents have, as well as what type of personality the firstborn is.

My daughters are 2 years apart, and I think that worked really great. They are still close enough to get along and play well with each other yet old enough to learn from each other.

There is no hard and fast rule here. Each family's circumstances are different and differing results are achieved. My two boys are 16 months apart and they get along like a house on fire. They do have their differences but we have not seen any significant issues. My partner was ten years old when his brother was born. The next brother is two years younger. As it turns out the two younger brothers and the parents have closer family bonds - in some ways making my partner feel excluded. (it has nothing to do with intentional stuff - just that the family shared a lot more when the two younger boys were growing up). So in answer to your question, I feel one to three years gap leaves them as buddies while growing up, particularly if they are the same gender. Cheers.

Well my kids are 15 months apart. My daughter is 18 months old and my son is 3 months, they were supposed to be 14 months apart but he was late. Ideally I would have liked 2 years apart but this is actually quite nice now that I have gotten over the initial shock of the idea.

I don't know if there really is a best age gap. My first two are one day from being four years apart, then there are two years between two and three, two years between three and four and five years between the fourth and the twins, they have all been fine with having another baby around, have never been jealous and I have never had any problems with it. I guess it would depend on the child and weather or not you think that particular child can handle having a sibling.

I have to say that there is no real set age difference; my older sister and I are fourteen months apart, and we fought like cats and dogs when we were kids; my two daughters are two years and nine months apart, and - although they got along famously when they were younger - they fight like cats and dogs,lol. I think some important factors to consider when deciding how much of an age gap you want between your children are: Do you want two babies in diapers at the same time? Do you want one child going through puberty while the other is still playing with dollies or tonkas? Ideally, it is the parents' personal preferences that should be the deciding factor, because you are the one who has to deal with the dynamics of your decision, whether you want them one year apart or five.:)

I think ideally, the kids should have about 5 years gap. Ofcourse that is for the parents not to have problems in bringing up their children.
