PickleBottom - this is all about you and is a bit odd TBH.
You haven't even mentioned him other than to say you miss him.
Can we focus on DS for a minute? How has he settled in school? Is he happy? Does he appear to enjoy his days? Has he made friends?
And what's with the apparant preference for DS over DD?
I do understand your feelings - my DS was 4years and 1 week old and I missed him dreadfully and felt that we should have had another year together before he started full time school. And IME there is something more vunerable about boys.
But...what's wrong with you lot?
Butter - Have I missed the point - surely HE should only be considered if it's in DC's best interests and not because mummy dearest misses her little one and wants him home whilst DD is in child care?
HE is taken far too lightly IMO.
YANBU to miss him.
YABVVVVU to seriously consider keeping him off school for anything other than illness, or extreme bullying or a funeral IMHO.
How on earth are you going to cope when he grows up and moves out?
