Is the 4 month sleep regression a real thing?

[creaser]

My DD is 17 weeks and has slept through the night from her last feed at 10.30pm for about 6 weeks.
Suddenly she is disturbing loads through the night, not feeding her as don't think she's hungry as when we do finally get up at 7 she's lazy with her bottle.
She settles herself at 7pm and is put down awake what's going on keep reading about this regression. Is it a real thing how long will it last and what can I do to stop it.

I think it really depends on the baby. Some of my friend's babies had it veeery mild and lasted just a bit.
For us, it was real. DD went from waking up just a couple of times for a feed (BF) to waking up every couple of hours or even less, sometimes not settling for a while. She wasn't upset, she was just awake and in a playful mood (at 4 am, I wasn't!).
It lasted a good 6-8 weeks and then she was more settled.

I don't think you can really stop it as it's a big developmental milestone and their are too little to sleep train (imo). We just dealt with it one day at the time, napping whenever we could.

Just repeat, again and again "this too shall pass". It's hard but then you look back and it feels like just a rough day rather than weeks x

My 4yr old DS never had it it but was much later to start sleeping through so maybe it just seemed that way. Good to know it's not forever I can cope with 6-8 weeks I think

Yes, it goes away and they settle into their new sleep cycles... until the next thing comes along, you know... teething, constipation...
