To let out spare bedroom to DH's friend or not?

[LilExhausted]

One of my DH's friend has moved to our city and looking for a short term rental for 4-5 months. We have a 4 bed house and 2 young DC- a toddler and a newborn. I am on mat leave which is generous. We are not in any need of extra cash but I feel tempted to suggest to DH to let out to his friend.
But, I am concerned that his friend may think it's not good that we are asking him to pay for rent for the room, I am not sure, just guessing. Also, I don't know how the grocery costs etc will work. We are in midlands and around my area, spare rooms are around 550-600.
My husband has known him for over 10 years, but I have only known him couple of months. My DS gets on well with him. I also feel uncomfortable breastfeeding around other people than just my family and I am also worried that I might feel like I can't move freely in my own house if he is sitting in lounge watching TV etc with my husband or toddler.
Can anyone please suggest if it's even worth letting out for getting extra £600 and some help with childcare as having an extra adult around the house helps but at the same time I will be stuck in a bedroom feeding baby as I definitely won't feel comfortable breastfeeding around him and won't be able to spend more time in evenings with my toddler.

I definitely wouldn't invite a male lodger with young children, and absolutely not with the expectation of leaving him alone with them or using him as childcare.
I doubt he'd want to live in a family home anyway, it's not exactly a good fit for a single man.

I agree with this. My daughter brought a friend to live with us(initially I didn't mind as he's generally a nice kid)but living with this lad is totally different. He rarely washes (he smells)sleeps all day does no laundry never washes up. I come home from work to a whole sink of washing up and him claiming he doesn't know how it's all been produced while I've not been in the house. He has almost doubled my food bill and I've now told him he has to leave as he's upsetting the household and winds up my kids. He pays board granted but his eating habits alone cost more than the board he contributes let alone the fact that my gas bill has gone up cos he puts the heating on when I go to bed and leaves it running all night. It's honestly been the most stressful 8months and I honestly wish I'd put my foot down and told my daughter no to letting her friend stay in the first place

No.
Fuck that.

No way. Offer him a stop gap to stay for a weekend as a friend but;

• you're going to go through ups and downs, probably frustrations with your DH because you're both tired and parenting two smalls is a lot. If you're going to hide away to breastfeed...it's just a bad idea.
• charging full whack to a friend is a bit crap, I'd expect mates rates and four months is a long time for things to go wrong, misunderstandings around groceries, bills etc which could affect the friendship, especially in the situation you're in on mat leave. And you want some bloke round the house all the time when you're trying to change nappies, take a nap yourself etc?

No part of this is a good idea.

Only if you are on the breadline and absolutely desperate for money....and even then I would rent a room to a stranger rather than blur the lines with a friend.

Absolutely not.

No, you've said you don't need the extra money.
If you're happy in your bubblet at the moment, don't bring in a whole lot of reasons to jeopardise that.

There will be days, your baby or child will be sick, or you all had a bad night's sleep.
Days you'd like to have family or friends call over.
Days you'd like to stay in pj's and stay home.
It'll be harder to get him to leave, if he can't find somewhere else to live.
