I am really struggling at the moment with Ds sleep!

We were co sleeping all night till about 4 weeks ago, now Ds goes to sleep in his cot then into our bed when Dh goes to work at about midnight. He slept through at about 6 weeks for about a month! So he has never been a big sleeper! And 9 months of continual broken sleep is really starting to drain me!

The problem is he wont stay asleep! Now i know some kids dont need much sleep and he is sleeping for about 3-4 hours from when he goes to bed! This is great but i am not getting much sleep from about 10 onwards! He is always re settled on the breast or rocked in my arms!His day sleeps are only little ones about 40 mins and he is having maybe 3?

i really want my gentle parenting ways to be rewarded with a child who sleeps well so that all the people who have said they must cry it out will be wrong! I am questioning my parenting and wondering if this has contributed to his sleeping, I cannot see how loving and being kind to my child would make him not sleep though!

Ds never ever slows down! Right up to when i am feeding him to sleep he is still jerking and moving his arms around! He is definitely a live wire!
We desperately want many more children but i dont know if i could cope having 4 of him! This is really making me upset cause i want him to have brothers and sisters! but at the moment it looks like we will be having just him

My heart says i am doing the right thing but my brain is saying i need way more sleep! He is a happy child and is never sooky or cranky!

thanks for taking the time to read my vent/cry for help! I hope it makes sense i am very sleep deprived! x
