I have never, ever regretted having my children. I love them sooo much. Your little one will bring you such joy. They will, however, push you to places you never knew you had, especially when you throw in lack of sleep, fatigue, self doubt about whether they are too hot/cold etc. Now is the time to set your boundaries - be really clear about standards of behaviour. Even work on some pre-prepared phrases to use if things get nasty, such as "im going to hang up now do we can talk about this later when we are calmer". Apart from milk, warmth, and cleanliness, your baby needs only love and protection. She/he already has that. X
