Huge congratulations Sarah, I'm so pleased your wait is finally over.
As you know I tandem nurse Jack and Grace at the moment. I plan to continue nursing until they both self wean so I have no idea when that will be! What I must say though is that it is incredibly hard breastfeeding through pregnancy and their are many hurdles...painful sore breasts, not wanting to be touched, diminishing supply, change in taste of milk, comfort or feeding?, not to mention colostrum...and then finally tandem nursing.
How much is K feeding in the night time now? I think it will go one of 2 ways really either he is not bothered by the changes and continues to nurse in which case you may want to think about weaning yourself or he will self wean before lo 3 comes along. All I will say is that if you plan to wean do it at least a couple of months before this lo is due ( or a few months incase this lo comes early too). I know you said you dont want to tandem nurse but just wanted to say on a positive note it has worked really well for me and its brilliant when your toddler can help with those early days of engorgement!
I'm currently training to become a volunteer breastfeeding peer supporter, really enjoying it. Its brilliant you have made it to 2 years breastfeeding, thats a real achievement and I totally understand weaning before lo 3 arrives! I may just have to find out about weaning myself whilst doing this course as I honestly wouldn't know where to start. I'm currently going down the road of don't offer, don't refuse - I assume when they self wean they just 'forget' the odd day and then it gradually becomes more and more often until thats it.
Anyway sorry for my rambling, congratulations again. I look forward to hearing about your journey on here.
Wishing you a very healthy, happy 9 months
