Since your Husband is dictating what "your" kids do... then HE should be the one ALSO... who amends his schedule... to drive them around/drop-off and pick-up and get them home and feed them too....
It is only fair.
(Sorry, I wasn't clear if this is your Husband or your Ex you are talking about, or both of them).
PLUS you have a baby coming. Where is he in all of this??? He CANNOT expect you.... to still be driving all the kids around to their "sports." You will need to tend to the infant/nursing/being there for naps and feedings. AND at night too.
Wow.. if that were my Husband (sorry, your Ex), I would be irked. Major.
The parents of the "step" kid... HAS TO BE the one, to shuttle their kids around .... not you. Or their Dad.
Really.... I would not put up with this.
Do you kids actually 'like' being in those sports??? Or are they doing it just to "please" their Dad?????
I would really wonder about that....
YOU should ALSO have a say in this, and 'control' over what your kids are doing... and the demands of it and the whole scheduling of it....
It does not sound like a 'modern' family to me... because, your Husband or Ex, ie: the "man", is still dictating... what you and your kids do... and how 'you' have to do it... and you have no 'say' in it all. That to me, is archaic.
If you are talking about your Ex, How does your Husband feel about all of this???? I mean.. it must really take up a lot of time... and plus you work too... and I am sure you and he have your own ideas/plans about what to do once baby comes home...
all the best,
Susan
