I just read a thread about sexism and movies and now I read several posts by parents who are chastising a mother who is tired, alone and frightened who wanted her ex to help with their child.
I expected the same concern for a frightened mother that was had for the female population being portrayed as high-heeled whiny idiots. This is real life not a silly movie and women are stronger, just like family, if we support one another.
My dh worked out of town for many years off and on. I know how difficult it is to care for a child alone. If nothing else, I called him bc I needed moral support while I bathed baby and me and sorted linens and sometimes wanted to cry along with baby.
OP needs advice, kindness and support. She does not need to hear from the mothering elite who can change nappies, clean vomit and pole dance at the same time. Her ex should answer bc not all illnesses are benign. If he is a selfish man who doesn't want to be a good father, I suppose this is a good time to find a support group/ friends/relative of some sort to help out with advice at the least if unable to get to OP physically. What if she needed meds or hydrating drinks? Those are also under the father's help definition. Having a child one day/ week should, if he is a decent person, include helping if the dc is sick.
I hope you are better now, OP and if he is a person who is not to be called upon in emergencies, make plans for next time. Make a Sick Kit.
Have everything you will need in a safe spot so you can take care of both of you without depending on him. DC comes first, emotions, etc. Sort out after dc is feeling better and you get some sleep.
