My best advice is this:
1. Work on creating a home routine. Set regular times to wake up, eat, nap, go to bed, and maybe potty training. Once you have those basics down then you can really allow your days to go well and orderly.
2. Remember the more time you spend in the house the more housekeeping you'll have to do. Most mom's forget that. It is good for children to be outdoors for fresh air, for sunshine, for free imaginative play and room to run and be loud. Your two are still little but it is good to get them out every day even if it is just for a walk around the block or some time in the yard watching bird.
3. Try to have one outing each week. Parents go both ways on this one too much and they are always running around or too little and they start to get cabin fever. Pick a library day or park day (picnic in the park is my daughter's favorite). Look for free activities at either Dallas Child or Fort Worth Child magazine.
4. You can't go wrong teaching your kids to pray and reading them bible stories in the morning, naptime, bedtime. One thing I wish I had done earlier was fill my house with time with the Lord. Sometimes we get so wrapped up in teaching them life skills that we forget to teach them how to pray and to listen to God's word. There are some great little one devotionals that tell stories or get a good children's bible and just read them one whenever they want cuddle time. Also fill your home with music during free play. It will help your attitude and theirs.
5. Don't forget to ask God what He wants you to do during this time. I too am a creature of routine, but I found that God was calling me to show my daughter the value of relationship and well as you know relationships require meeting of two different personalities and souls. So my very outgoing daughter's idea of time together is not usually on the schedule she wants to have a picnic for breakfast or play trains before bed. So just go with it and habit train secondary to building that relationship with your little ones. Observe and listen more than you instruct and they will surprise you how much more they will absorb from your actions than your words.
