I planned to take 6 months off and everyone told me my priorities would change once she was born and I'd want to take the full 12 months off. Well 5 months in I was going insane, I was so bored and over it and pestering work to get back to me about what my part time arrangements would be. I was in my element when I got back to work 3 days per week. I ended up spending a few days a week at the shops, a few days with my parents (I know you don't have family nearby) some time trying to clean with a baby, and tones of time trying to get her to sleep lol.
I'm actually nervous about having another baby because I'll have to do the SAHM thing again! Though I won't put as much pressure on myself to make the baby sleep next time around so hopefully it will be more enjoyable.
