after spending a week alone with my kids, i can fully understand how hard it could be for a single parent.
that said, please think the vax over very, very carefully.
why are you so stressed (stupid question, i know)? is it just the sleep deprivation? if it's just sleep deprivation, i know my opinion is not going to be popular but i would rather put my kids into some sort of sleep routine that they are not going to like at first BEFORE taking any vax that could seriously paralyze me and leave my kids even more vulnerable without a mama to take care of them.
i'm not advocating leaving your kids alone to cry themselves to sleep but just setting up some sort of routine and sticking to it. if the kid needs to cry in your arms, so be it. AP is ideal and what's even more ideal is when there are two parents to take shifts in meeting the kids needs. when there is only one parent, you do what you can and leave the rest.
when i am sleep deprived, my immune system shoots way down overnight. i have two kids who hate to sleep but sometimes i just NEED to sleep and badluck to them. yeah they will mutter/grumble while they lie down next to me (we co-sleep) but it's not the end of the world for them, seriously. there are much worse things that could happen (like thier mama being very ill and her health withering away). they know i'm there, they know they're not alone - they just want to stay up more and keep playing. i cater to thier needs all the time and i have needs too you know? PLEASE, you need to take care of yourself mama. and having the flu vax is NOT taking care of yourself and it's not doing whats in the best interest of your kids either should anything happen to you as the result of a vax. you are all they've got, just remember that.
i don't know.. that's my opinion. i would try to minimize the sleep deprivation AND up my vit's - lots of CLO, zinc, vit A and C. the vax would be my absolute last resort and even then i'd still have reservations.
