Is this still 4 month sleep regression?

[Waffle12]

Hi all

Dd is almost 6 months now.

Early weeks were full of wake ups, but then we settled into a pattern of probably 2 wake ups per night, and first stretch of sleep lasted anywhere between 3 and 5 hours. Nearly always breastfed back to sleep, and slept in moses basket in our room.

She was never great at napping in the day and if we were at home she would only nap on me.

At 4 months- bam! Night time sleep got worse. More wake ups. Assumed this was 4 month regression.

At about 5 months we got a run of about 3 nights where sleep seemed to improve, so I thought we may be coming out if it. But then she got a cold and was all snotty so had 4 horrendous nights where I was up constantly with her.

Since then the sleep hasnt got much better. She is almost 6 months old. The longest she has gone recently between wake ups is 3 hours. But more often than not she will only last 1.5 hours, bit can be alot shorter. She very rarely self settles. We try and shhhh or pat to sleep but it doesnt work. Rocking to sleep will sometimes work but most of the time I end up putting her back on the boob. We dont try for too long before I put her back on, as she has a older dd who needs to get up for school, and the crying tends ti wake her up. Also I suppose as I know it will work. She isn't always hungry, but will stay attached for anywhere between 20 and 45 mins. I have to try and remove my boob, which quite often will wake her up. She is now in her own room (for past week and a bit, with a monitor) as she just doesnt have enough room in her moses basket any more. We have been successful in getting her to nap in her cot now in the day, but night time is still a nightmare.

She is ebf. I cannot express as I hardly get anything out. Have tried formular a few times to give me a break and see if it will help her sleep but she wont take it, although I have to admit we have not been very persistent. I am really struggling with this. I am a bad sleeper anyway, but am now not getting any sleep and am getting so angry and frustrated with her which I feel awful about. DH gets up with her occasionally, but I mostly deal with it as she ends up on the boob anyway.

Could this still be the 4 month regression? Most things I read say it should only last a few weeks, but we are nearly at 2 months now!! Any other ideas? She doesnt seem to be in pain, she doesnt have reflux. She just seems to have trouble staying asleep and getting back to sleep unless I give her my boob.

Please help!!!
