i also preferred same sex siblings initially . if i hv a #1 gal , i dun mind #2 gal etc
BUT , i hv a #1 boy , i prefer gals coz they r closer to mummies .
since we are at this topic , i read an article , it says for those who wants to try for a 2nd kid , it shd be ideally after #1 turns at least 18mths . if the gap too close , our wombs cannot rest sufficiently , hence #2 will be in a lesser position than #1 .
probability of #2 being premature / smaller is higher too if the gap is too close .
the above was just what i came across from the article !
