I am 10 weeks 4 days pregnant after miscarrying in August. I am so excited and so happy, but our DS just turned one, and I am having the hardest time keeping up with him throughout the day in the midst of extreme nausea and fatigue. I am also a new SAHM (as of September) and I feel like our routine wasn't that solidified to begin with. Any suggestions or ideas from other second time mom's? I want to make it through the next few weeks without totally sucking at being a mom. Not to mention our house is a disaster and my DH has been eating cereal for dinner for like a week

totally drowning.
Re: Second time mom going insane
Second, none of us have this crap figured out. I've been a SAHM for nearly 3 years (working sporadically but always returning to SAHM status). Do what you can when you feel well enough. You'll come out of the fog and be back to "normal". Stop thinking we're super moms who crusade through our pounding headaches, nonstop nausea and vomiting, earth-shattering constipation, and fatigue so bad we can only make it to the potty and back, to accomplish all the pinterest crafts with our kids. We're all struggling. You're doing what you can. And if I'm being totally honest here, sometimes even when I feel like I can, I don't (self-care is important, too).
Third, it takes a while to find a good, working routine at home with a toddler. In my case, my children made our schedule. They already followed a loose routine and I just learned it.
Just so you don't think I'm blowin' air up your tooter, when baby #3 comes, I'll have a 3 yr old and a 1 yr old. I've gone through the same feelings you're talking about. Stop putting so much on yourself.
The adopt u.s. kids commercial slogan is actually what snapped me out of my insane obsession with being a "perfect mommy" : you don't have to be perfect to be a perfect parent.
Also, we have s STM check in every week where we discuss this type of thing so make sure to post there.

Do not the feel guilty though. Soon you will feel better and get some energy back and while things still won't be perfect, they will get better. Super proud that we've only eaten out twice in a week and that I have managed four loads of laundry in two days.
If you need to ask a friend/ family member for help. It sometimes help me get the chaos under control.
I'm a FTM and my house is a mess! I arrive home from work so tired that the only thing I can think about is food. DH is trying to get as much done as possible but I definitely don't feel guilty. I'm gonna nurture this baby for 9 months and push it through my vagina. He can handle the house for now. He should also be used to by now since during the 2 years I was getting my MBA I also told him it was his responsibility to cook and clean while I was in class/studying. Marriage is a partnership. Being a SAHM doesn't make you fully responsible for raising your kids and maintaining the house. It should not be a 24/7 job. DH must share chores when he's home.
I hear you on the clingy kid thing. My DS is two and wants to sit in my lap all the time. To make it better my cat is extremely clingy when I am pregnant. Yesterday during naptime I had my son holding my hair and my cat sitting on my chest. I'm at the point where I don't want to be touched.
I don't cook dinner every day. Meh. Don't worry it will pass eventually and they won't hold the 'bad momming' against us. And hopefully your husband is supportive and understanding. Mine is fine picking up dinner a few nights a week because he knows how worn out my body is and I'll come around.
