For me there's two things going on here. The first is how dangerous or not those things are now in this household we're pretty laid back to the point that lots of mummy's from the toddler group think I'M neglectful so here's how I would react!
- gives DS, 9 months, milk (EBM) which has been lying around half-drunk for 4-5 hours
not too worried, tbh I read some interesting studies about the extent to which excessive cleanliness idea about the sterisling, throw bottle away if they've been touched etc things can backfire.
- thinks it's hilarious when DD (nearly 3) wants to play lean back on a chair until it falls over.
Now I don't think its funny (DS does this) but I did get to the point of saying well fine you'll fall off you know. I would check for really dangerous tuff but then let him get on with it usually popping a pillow or something in the likely crash zone (I dont' know because we've realised that DS developmental disorder means he DOESN'T learn from pain)
- doesn't think to change DS's nappy except maybe once or twice in the whole day so he ends up with a sore bum because he's been sitting in poo for hours
This does annoy me, DS doesn't notice sensation/pain/discomfort so you really do have to check frequently with him and its just one of those things you learn to do every hr or so as a parent. Its not massivly dangerous but it is leaving your child uncomfortable.
- leaves DD in the bath by herself and doesn't have a hand out when DS is in the bath and he has fallen under the water and been really upset a few times (he would never leave the room when DS was in the bath)
yeah OK I'm a terrible mum, I leave DS in the bath all the time have done since he was 2, I go into the next door room and tidy papers or something or nip downstairs for a bottle/towel etc. Nowadays he has a stool and can get out of the bath on his own so I just let him get on with it. The rest of the time I take a book and cuppa in there with me.
Mind oyu not sure how old your DS is but I never left him on his own until he could not only sit up but also stand and walk.
- never bothers with suncream (although neither has ever got burnt)
do you mean they've never got badly burnt or that they literally havn't ever got even a bit red? if they havn't ever goen red then actually he's judged the severity of the sun pretty well. I was VERY careful with DS until he turned 1 but after that i just judge it. If we're out for longer than an hour on a scorcher of a day i take/use suncream. If he has his top off i use suncream but I don't regulary put suncream on. I have to say this summer except for 2 days at the beach and one lone week in June when it was hot enough to have the paddling pool out I don't think I really used suncream at all.
- leaves DS unstrapped in his highchair while he goes upstairs to the loo etc - did this with DD as well and she once fell out and hit her head on the tiled floor
Yeap thats dangerous, actually I wouldn't leave them in a highchair on their own.
- OK and here is the really bad one - has left DS in the car by himself while he and DD went to the supermarket - this happened a while ago (in the SUMMER) when DS was only tiny as well - he got a right bollocking for that though and hasn't (he says) done it since
thats neglect and thats the one you need to focus on. I can imagine me or DH doing any of the above, but leaving a small child in a car is just completly out of line, anyone else who took your baby out and then left them alone you woudl report to SS/police - why does he get off?
Now for the second part, which for me is almost more important. The issue is he is doing things that YOU FEEL put your children at risk. To me alot of this says that he is laidback /uncaring nto only about the childresn safety but also about your relationship. It feels like he isn't taking any of this very seriuosly.
