Awww- it must be soo nice to have him back.

The longest I have been away from Keira is 3 days and that was hard!

Exactly!  My DH is more daddy to our niece and nephew than their biological fathers aka the sperm donors (in fact my cheeky nephew used to call his dad Uncle *my DHs name* just to annoy him lol).

Oh Babe, that's beautiful!

I have a niece and a nephew that like you were completely accepted by their mum's husbands and although neither of them were ever formally adopted their 'real' dads are their stepdads.  Both have younger siblings that are biologically related to both their mum and dad but they're not treated any differently by either parent.  Both have since grown up and got married and my nephew had a baby recently and named him after his stepdad.

I think that your should follow your heart. The inheritance thing does make it a bit trickier. Members of the family are suppose to be equals, and so all 3 of the children should get their fair share. I would most probably take into account the amount of inheritance the two older children will get and factor that into the amount the younger (unborn child at the mo) would get.

I come from a kinda blended family, I have 3 older half sisters and an older half brother. But there is not one hint of his/her children. We've always considered ourselves full brothers and sisters (we have a younger sister and brother as well). So find it kinda weird that some couples still have that his/her children mentality.
