@Moonshine160 ive not read the whole thread. But I have read all your comments. Your post resonated with me. I hope I can provide you with some reassurance.
I had a 5lb 12oz baby boy at 40 weeks. He weighed 10lbs at 10 weeks. He was exclusively breastfed until 6 months. Other than I expressed and topped him up from the lid of a bottle, like a cup. So he was sipping rather than sucking & no nipple confusion with a bottle. I really only did this for about a week when he was a week old when the midwives wanted to know what he was having.
I too had a heavy let down and would often end up covered in milk at the start of a feed. I found a squeeze of my boob into a muslin cloth or Breast pad got rid of the first rush and then feed. It was less messy and he had more hind milk than fore milk.
i know what you mean about him looking dinky. My son had a massive head and a tiny bony body. Even at the time I thought he looked like ET ! He bounced below the graph in the book for a long time. Often below the 2nd centile.
at 6 months he was chubby. Till he learnt to move!
he is now a very lean rapidly frowning 14 year old. He is only gaining to average weight for his height because he’s focusing on muscle growth in the gym! He’s also now taller than me.
despite now being a fantastic cook/chef he doesn’t overeat. He knows his limits in the moment and only eats what he wants. This regularly means he eats smaller meals and a bit more later ……… JUST LIKE WHEN HE WAS BREASTFED !!! He doesn’t like me saying that now - but it’s who he is!
I wish I had the self regulation he does..
just keep doing what you’re doing. If his nappies are wet and dirty regularly he’s getting enough.
the only trick I’ve not seen you mention, is giving him a wash to wake him to feed more. Either a damp flannel or a baby wipe down the back of the neck and back to wake him to feed for a few more minutes. You may have to wind and settle him and feed again for 5 minutes. It might give you longer stretches between feeding.
but ultimately you’re his mum. & what you’re doing for both of you will be the best! You’ll get there. You just may or know it until you stop and look back. xx
