Quoting 3rdxsacharm:" Between my expected LO and my other two. My oldest will be 14 and my youngest will be nearly 12 when ... [snip!] ... worry she will be exceptionally jealous of the LO because of this. Anyone had similar situation? Thoughts? Advice? anything?"
I dont know if this is going to help at all but worth a shot
My brother & I are 8 years apart. My father & his father are different. My biological father left when I was 6 weeks old and then when I turned 2 mymom met my 'dad' and he adopted me when i was 3. My brother cam into the picture when I was 8 - there wasn't much resentment or jealousy - i had issues here and there about like things being different but nothing huge.
After a year or so my 'dad' and his family turned on me and paid WAY more attention to my brother, for example birthday he would get more money then me (still to this day my bday was in September I got $50 his birth was the 28th of this month and he got $100) ... when my 'dad' would complain to his parents about problems with me they would tell him things such as "why worry about her she isn't even your child". So my 'dad' and his family changed after my brother was born. I would just try and keep things VERY normal and make sure she isn't treated differently and I am sure things will be fine.
