House is too small

Idk what to really even do. My boyfriend bought a house when he was 21, he jumped the gun because not many 21 year olds own their house. He didn't think about long term things. Such as having a family. Well I moved in about 2 years ago. For 2 people it was okay, the problem was having only 1 bathroom, and the kitchen but being 2 people I've made it work. Well now we have a 3 month old. And this just doesn't work anymore. It's somewhat okay just having him but we want more kids and 2 kids in the house will NOT work. We also have 3 medium size dogs on top of that. And he just doesn't see it, he thinks we need to get the house paid off then buy another house. Because he's paying the house bills because I didn't make enough to help, and right now I'm going to school full time(ill be graduated in a year). Problem is that'll be about 10 years from now.... he thinks it'll be fine. So how the house is, like I said we have one bathroom, the kitchen I don't have any counter space, I have this little island you can move around and that's it. Because it's one counter top, double sink, other counter top, which the microwave takes up that whole thing, and the other side I have my keurig which yes I could move, but problem is I don't have anywhere to put it. All the cabinets are filled, I'd have to put it on top of the fridge if I moved it. So off the kitchen is a bedroom which is our sons room now the size is fine, but I've been getting very frustrated today because I'm trying to go through all his clothes and the closet is just a couple of shelves really maybe goes a foot back so I have no idea where to put his clothes that he won't wear for a while because I already have that closet and his small dresser filled. So then you go up the stairs and it's just this room you end up in is really small it's weird best I can explain it it's like a foyer that goes to our bedroom. I mean I guess one day that could be a nursery but you'd walk past it every time you go to our room especially with the dogs... I couldn't decorate it the way I want because it goes directly with the stairs.(yes I love decorating so it does matter to me) and right now with our son being 3 months old I have his clothes and some toys I have no idea where to put right now some toys are thrown on the front porch along with other junk and it just looks so trashy to me and he thinks it's fine. I don't want someone walking up the front door and seeing all of that. Our back porch we can't fit it because that's where the washer and dryer are and that's all that can fit. And the basement you have to crouch down the whole time to walk down there it's a pain in the ass. I know some people probably think I sound ungrateful like he does, but when you're in my shoes you'd understand how frustrating it is, and not doable for 2 kids, 3 dogs and 2 adults. It's barely doable with one kid. And when he's only 3 months. I understand he's paying the bills, that he is right about getting it paid off then moving. But I just don't think he see my side or frustration when it comes to being the caretaker. I'm the only one who cooks, cleans, and he takes care of our son to but pretty much only when he has to. I just wish he'd see that this just can't work.. 😞 I'm just so frustrated.

****thanks... but I guess it's hard for anyone to understand when you haven't seen the house.... I've gotten rid of a bunch stuff to make room and have made stuff for storage and I still have no room... I just don't want my kids sharing a room especially if we have boy and girl. And like I said I barely have any room for my 3 months old stuff how would I do that with a toddler and another baby... the room he has pretty much only fits his crib and dresser and his box of toys. I like them to have their own space no matter what age. It'd also be nice to sit down together as a family and have dinner but we can't do that because we don't even have a table or anything and can't put on in here... I mean it's great anyone who made it work but I personally just can't make it work here. Again it's easier said than done, and easier to say since no one knows the layout.
