I was happy to get to 12 months, so very happy to get to 15 months.
More important for me was not the length of time, but the exclusivity of breastfeeding. I didn't want anything else to touch her lips!
Next bubs I will aim for 12 months again, and just take it as it comes after that. I'm not really interested in feeding past 18 months, but thats just me.
The early morning one was really hard to drop as it was such a comfort feed for her, and just sooooo easy for us as parents. I think she would have been happy getting that one until she was 10 years old!!
