First -- how often do you and your husband have dates, or spend time together just talking about each other? With the baby around, this might not be top priority right now, but it needs to be. You have to remember that before you were parents, you were a couple.
Your husband might be feeling left out in a lot of ways because you are so enamored with motherhood that you've forgotten to be enamored with HIM. I think it happens to a lot of us.
I'm not sure how many people realize that having a baby is hard on a marriage for that very reason. You get caught up in the blissfulness of mothering, but men are easily overwhelmed at fatherhood and your asking, giving tips, etc. (which he will view as nagging, no matter how nice you are about it) only reinforces his feelings of inadequacy and makes him pull farther away.
Rather than trying to focus him on the baby, take a few steps to focus yourself on your husband. Start by greeting him at the door when he comes home (rather than hollering from the back of the house where you're playing with the baby). This is assuming you're a stay-at-home mom. If you're both working, make arrangements to share drop-off and pick-up duty at daycare. Having a "job" will help him feel needed, and less like you're the only one who needs to be involved in parenting. (letting him pick up is best -- he'll feel like her knight in shining armor when he sees her light up as he walks in the door)
Once everyone is home in the evening, let the baby play in her crib or playpen after dinner while you ask your husband about his day.
And make it a point to reserve time each day for the two of you. We try to make 8-9pm our "couple time" We might watch a TV show, eat ice cream together, play cards, whatever. And make date nights a priority. You may feel guilty for leaving the baby, but believe me, she needs you to have a happy marriage as much as you do.
As far as the baby: Speak less. I have learned that the less involved I am in "Daddy & Me" time, the more fun they both have.
One day, when she's awake and happy, get out of the house for about a half hour or so and leave them alone together. You might need to prepare him for it in advance though. Maybe go get a manicure or a haircut or something where it's just easier not to tote the baby along, but you won't be gone that long. Instead of telling him instructions, simply make sure he has what he needs (bottle, paci, etc.) If you want to let him know what her favorite toys or activities are, write them down or type them, leave the note on the table, and let him know it's there for his reference. On your way out the door, thank him for letting you get out and say "y'all have fun! Daddy's going to show you what Daddy's do for fun!"
And don't get upset if you return to find them both watching football, or she's been eating ice cream or whatever. It won't hurt her a bit and Daddy's just do things differently than we do :-). (I believe my daughter was about 4 months when I caught her grandfather feeding her peach cobbler -- she'd never even had baby food! I was mortified, but they said "you can't tell us what to do!" We all survived, and she adores her grandfather.)
And try not to ask 20 questions when you get back. (did she have a poopie? when did she have her bottle? how many ounces did she drink? etc. etc.).
Sorry for being long-winded, but I hope some of this makes sense and helps your predicament.
