Oh yes! I think some of it is hormones and tiredness, but I think a big part is that a baby brings a whole new set of responsibilities into your dynamic and so many couples (myself and included) don't consciously renegotiate how the household/family responsibilities should be shared. In many cases, the new mother absorbs most of he new responsibilities and the father’s life continues relatively unchanged, which then builds resentment.
All is not lost though, my husband and I did eventually iron out a new dynamic and by the time baby number two came, we were working as a team and I was no longer daydreaming about leaving him!
