I am curious as to how that counseling session went.
The fact that he was extremely touchy before, and now not all, is troubling. A major change like that suggests to me that something is wrong, but it could be any number of things, so unless he tells you what is wrong (if he even knows)it would be pretty hard to correct.
...Otherwise I would say that the constant responsibility and monotony (exhaustion, drudgery, lack of free time) of marriage and parenthood can have a similar effect on most marriages, and you could try a short vacation (no kids). I think people kind of lose themselves when they marry--especially women, since we do feel "expected" to do so much in service to our families, it is exhausting. It's possible that men feel something similar---too much "have to" and not enough "want to"---that can take the spark out of anything!
My husband and I delayed our honeymoon until about 7 months after the wedding, for practical reasons, and I remember being very relaxed and happy on that trip, in contrast to the months before, which involved a lot of transitions, changes, stress, and work. I felt like it refreshed not only me personally, but the relationship in general. It's easier to bond 1:1 without kids. There were already kids going in, for us, and it sounds like it was the same for you and your husband. I think this makes it harder.
Anyway, don't give up! Keep doing the counseling, do special stuff just for you, and try to find things to share with each other---like I just got my husband started reading a series of books that I loved, and I can't tell you how happy it makes me to see him reading them every day, and hear him laughing out loud. Just knowing that he enjoys the books as much as I did, makes me feel closer to him! Oh, and we have been gardening together, too.
