Colostrum and breastfeeding while pregy

I have asked questions about breastfeeding while pregnant before. At the start of my pregnancy etc.
Well last night my nipples were a bit dry (as they get sometimes) and so i tried to hand express some milk to massage into them as thats whtat ive always done to heal my nipples. And what came out wasnt milk and was definately colostrum.
When i was pregnant with henry i started leaking colostrum at 18wks but thought that i would continue making milk this time since im still feeding henry. Henry still feeds morning and night.

My questions are:

Will my colostrum run out or is it like breastmilk in that more demand more supply type thing?

Colostrum is fine for henry right?

Should i now be giving henry something else to drink (like formula or milk) as well in the morning and evening or will colostrum be enough? (he eats 3meals a day and has water when he wants it from his sippy cup).

These probably sound like really daft questions but they are getting to me a bit. I honestly thought id keep making milk until maybe the last month of the pregnancy.

Thanks in advance for help

so henry could still be getting milk? hmm didnt even think about that. Our bodies are truly amazing in what they can do. I guess i shouldnt worry too much. He hasnt been complaining - just being a normal toddler with latching on then off and then on then off before settling to feed

Henry has just turned one. He eats very well.
Good thinking about LLL website. I tried to ring one of the support people a while back to see if i could join a coffee group or something as i dont know anyone breastfeeding but no one ever got back to me.
I am very greatful that he hasnt weaned as im not ready to give up that closeness with him yet. But i have said from the start i would feed until he self weaned which means i guess that i have to be willing to let him do that when he decides even if its a bit earlier than i would like

lol i never even noticed, shocking preggy brain.

I know I sound a bit of a stuck record but kellymom as usual has some great info on the topic

kellymom wrote: The changeover between mature milk and colostrum production begins, on average, between the 4th and 8th month of pregnancy, but some mothers start producing colostrum somewhat earlier than that. Many mothers who nurse through pregnancy have noted that their milk contains mostly colostrum during the last month before baby is born. You will continue to produce colostrum throughout the latter part of your pregnancy - your older nursling cannot "use it up"... If your older nursling is getting a good quantity of colostrum (either before or after birth), the natural laxative effect of the colostrum may cause him/her to have looser and more frequent stools. The stools should return to normal once your colostrum is completely replaced with mature milk... At birth, the sudden decrease in progesterone and estrogen levels (and resulting surge in prolactin levels) that occurs with the birth of the placenta causes colostrum production to kick into high gear and signals your milk to "come in." Once your baby is born, the amount of time you produce colostrum is limited, since your mature milk will begin to come in within a few days.

weegee you legend - that's the article I had read. I forgot it was on the kellymom site.

Angel4, I cant believe Henry has tuned one as I remember when you first got pregnant and he was only 8 months...scary how time is ticking by!

Sorry for adding that randomness to the topic!
