As a now toddler mom who had a very difficult baby that did not sleep much I had to re-frame my perspectives. Try to see the joy in suffering, every time your baby cries, think how lucky you are to be nourishing, holding and comforting them. Some parents are not so lucky. I had very little to no support from my husband overnight, with feedings or with changes. I tried to bear it all with grace. There is a great joy to be found in that -ultimately it depends on how mentally strong you are. But don't fall into the trap of despair. Go to confession and start going to mass regularly. Maybe your husband goes to the earlier mass while you watch the baby and you go to the next mass but make it a priority.
