Sex of baby

Melanie.
Do you have 2 or more kids only a 1-3 years apart? If so, what's their sex? I hear if you have a baby one after another the sex is the same. For example, I have a boy 14 months and if I have another one now, it'll be a boy again. Is that true? Your cycle changes every 5 years and if you want to have a diff sex, you have to wait for your cycle to change? Please tell me you have diff sex babies and you had them within a few years LOL
