While a new baby will bring lots of joy, it is also a lot of work. Adapting to the demands of a new baby is both emotionally and physically tiring especially throughout the first few weeks.
It will take time to adjust to the changes that a new baby will bring and life will not be the same again. Often it may feel that you no longer have time for yourself and if relationships become strained, it is easy to reach breaking point. Until a baby settles into a routine, there may be many sleepless nights which can make you feel very tired and irritable.
If possible, try to rest when the baby goes to sleep so that you feel refreshed when they awake and are able to cope with the demands of being a new parent.
