M.P.
In my experience this is very normal. My advice to you is to try not to ALWAYS give in to the temper tantrums. You don't want him to learn that that is an effective way of getting what he wants. On the other hand, by all means, if he wants Mommy, give him Mommy. If he wants daddy, give him daddy. Of course, only if you/he are available. If you aren't doing anything really important,show him that he is important enough to stop and make time for. They are only little for a short time and one day before you know it, he won't want mommy OR daddy do do anything for him. Enjoy this time with him now!
Also, I wouldn't be too concerned about how he will act when your husband is at work all day. Kids tend to do that kind of thing more when BOTH parents are around. In the evenings, my son will be choosing about who he wants for what but during the day he knows he just has mommy and is fine with that :-)
