My OH thinks our son has attachment issues

OH has said a couple of comments recently that our LB has serious attachment issues and we need to nip this in the bud. I don't know if it's true or what can do to try reduce it.
If I was to pop out to the shops LB will have a complete meltdown about not coming with me, "I will miss you" etc. I always reassure him that I will be back and give him an idea of something to do, e.g play X with daddy. He will cry a lot but then maybe after 5 mins he does calm down and he's fine. He is the same when his Nanna looks after him and I have to go to work, and sometimes when I drop him off at school. Is this an attachment issue or something about separation anxiety maybe, how can I help him manage this. He's 4 years old.

NHS job

Anyone work for the NHS and does 12 hour shifts? How do you work around childcare and your partners job?

He has no respect for anything to do with me.

Husband and I decided to separate 3 days ago. I've been sleeping on the floor in the kids room, and we both have to stay in the same apartment for a while. He wont stop pushing little things and I am reaching my limit. Photos in comments

Toddlers

How often are your toddlers asking for food? My oldest who is 3 just finished a whole plate of food and not even 10 minutes later he’s requesting more food. I know he’s going through a growth spurt, but how do you respond to this.

Is this normal?

Is it just my husband that does this? He is able to work from home via his computer and in the mornings and evenings he is on there doing his job. When he is done for the day he tends to stay in the room and either play video games or watch something. He will occasionally come out and play with the girls for a few minutes and that’s it but when I really need him he says he is busy. My daughters are both 1 year old now and I am just wondering how much involvement should he have with them now?
Idk if this is the norm or not…..

Identity crisis?

Am I the only sahm who feels like they have lost their identity??? I don’t make money for my family, when I used to make great money. But I refuse to drop my under a year old baby off with strangers.
My husband works so much. But I have no control over bringing in money and I’m a control freak type of person! I feel l like I’m losing my grip because we are kind of broke, but day care would only eat up my income anyways! So what’s the point. I’m a workaholic and now I’m just a twitching bum.
I wish I could work from home but so far that’s a fake dream. I’m almost 9 months pp, and I just need to know these awful mood swings and depression will end soon! Send wine!

Saying NO to buying toys etc

5 year old is getting really envious of others. He is obsessed with items that other kids have at school. I am pestered daily to buy these things in a different style when we already have 3 others. I have seen parents just buying stuff their kid likes which I don't necessarily agree with even when i can afford it. How do you deal with it?
