New to this, so please bear with me. I have two children - boy aged 12 and girl aged 8. Frozen as embryos, from the same batch of harvested eggs, but defrosted 4 years apart. They are ferociously jealous of each other and spend every waking moment in competition with each other, and fighting for my attention. The younger is the most dominant and has always wanted to do everything double quick, as if she were desperate to catch up with her older brother. One of those babies who wanted to sit up when she should just be rolling over, walking when others were just crawling etc. Exhausting. My husband and I have a strange theory (that others have remarked upon) that perhaps they should have been twins (I think I'm right in saying that medically they kind of are, being conceived and frozen at the same time) and that our daughter and son should really have been the same age. If you met them, you'd think they possibly were: others have made that mistake. She is almost the same height, reads as well, writes as well etc. And she is also a huge tom-boy. Q: has anyone else, with a similar history, experienced anything like this? We'd just be interested to know whether there is a pattern...or whether anyone has done any research into this? Thanks
