AIBU for not telling husband to pick up both kids?

[ViceLikeBlip]

TL:DR husband offered to do school run this arvo. He forgot one of our kids. He is now (very angrily) claiming that this is all my fault for not telling him exactly how many kids to pick up. AIBU for thinking he should be able to remember how many fucking kids he has for himself?!

Details: I'm stuck home with 8yo isolating, so I needed someone to pick up the 10yo and the 5yo from school. I'd found someone for the 5yo, but I was struggling with the 10yo (all the Yr 5 parents I'm friendly with also have yr3 kids isolating). I didn't really want to ask the first mum to pick up both my kids, because yr5 finish 20 mins later than reception, and I felt bad asking her to hang around for an extra 20 mins in the baking sun.

So I asked my husband for our neighbour's number as they have a granddaughter in yr5.

The message I sent my husband went "do you have X's number? I'm looking for someone to pick up 10yo from school". He very unexpectedly replied "don't worry, I can leave work early". I replied "will you go straight to school?" just to check that he meant he was going to do the school run, and he said "yes, straight to school", so I texted my friend and said thanks very much but actually I didn't need her to get the 5yo after all. Husband then picked up 10yo, but completely forgot about 5yo.

Now, in my first msg I hadn't mentioned 5yo at all, because I wasn't actually asking my husband to do the school run. Should I have at this point messaged back "and don't forget the 5yo also exists"?!! Fwiw husband does the school run once a week every week, just not normally Tuesday, but the arrangements on the day he does normally do it are identical to Tuesdays (ie no one has any after school clubs or anything. 5yo never has any after school clubs)

Even those of you who would have forseen this exact situation happening, and who would have reminded him of the other child, do you actually believe its my FAULT for not reminding him?

Have any of you been outside recently?! It's not "hot", it's hotter than Satan's bloody ballsack! Of all the ways in which this scenario could have gone better, no one is going to convince me that the best course of action would have been to sit an 8yo child in a car in direct sunlight for 20-30 minutes in 32° heat. Its not such a massive deal to call in a school run favour - both potential helpers were people who I have similarly helped out in the past. But an actual parent would still be the better option!

Ps I do understand that some people have important, high stress jobs, and leaving early would be very difficult and would definitely constitute a favour. My husband is not one of these people. If he could leave at 2, that's because he was finished for the day.

Of course people have been outside today and yes it is hot, but people travel, shop, drive (without aircon), go about their daily lives.

My DB is a postman, been out three hours today delivering mail, do you think he should say "not doing this today, its too hot? The sun is directly on me and I am having to walk miles? Do you think that road workers, working with hot tarmac have had the day off? People dealing with accidents on motorways with sun on them are saying, sorry can't collect your vehicle or give you medical care, it's too hot.

Well you are very lucky that you and your partner are available so easily to deal with pick ups, should make life easier for you.

Hopefully the need to communicate will not fail in the future.

I didn't refuse to go out in the sun, it's not like I said "if I can't find anyone to help me out, then the kids will just have to sleep at school tonight"! I made a judgement call that if I could get hold of X to drive my 10yo home (with her own granddaughter, who she was already going to collect) then that would be better than making my young child sit out in the sun.

I have collected X's granddaughter for her on a number of occasions. This is quite a normal neighbourly thing to do. But I've never phoned this lady directly because it's her daughter in law (the child's mother) who has always liaised with me.

Although if your 8yo has put in a full day's shift with the police today, in full riot gear, then I guess I can understand why you think I'm being soft on my kid.
