Is there such a thing as a 5 months sleep regression?

[EllaWt]

Our 5 months old has decided she won't nap anymore and this is now resulting in nightmarish evenings and a greatly reduce milk intake as she is so tired and irritable.
I have tried everything, in the cot, in our bed, pram, baby carrier, car ... she will just doze off for a hot second and by the end of the day she is just so cranky that she often ends up going to bed with a mini feed (90-100ml) after much crying. I'm so sad to see her struggle so much and worried that she ends up eating less than she needs. Is this a phase and is there anything we can do to help her?

You need to help her nap. Sleep deprivation is more damaging to babies than it is to adults, and you no doubt know how rotten it makes an adult feel.

What is currently happening with her naps?

How often to you try to get her to sleep?
How do you help her get to sleep?
Whwn and for how long does she sleep over the whole day?

Was sleep different previous to this? What was it like before and when did it change?

@FATEdestiny so mostly I try to put her down in her cot... i do a little routine and then put her down. She fusses , i go in to calm her down... and so on until she starts screwing bloody murder. Even when she shows signs of fatigue the second she realises its nap time she's sooo awake and starts moving around like a maniac.
It's a bit better in the pram / baby carrier but she'll wake up the second I stop

Oh and sorry she's never been a star napper (but she's a superstar at night and has slept through since she was 1.5months old) but previously after much persuasion she would nap.

It's been about 2 weeks... this week is worse because we're on holiday at a cottage so new scenery

Yeah, that's nowhere near enough help to get baby to sleep. They need significant help to go to sleep. Just "put you down, now go to sleep" just won't work.

Some tried and tested things that help baby go to sleep:

● Sucking - dummy or feed to sleep
● Movement - Bouncy chair, pushchair, rocking in your arms
● Secure Feeling - being held, enclosed in a swaddle, next to you in bed, your touch, your heartbeat
● Going to sleep where they stay asleep so not being moved or put elsewhere once asleep.
● Not hungry, well winded

To be clear- your baby is likely to need all of these, or at least most. Not an either/or.

Also avoid over-tiredness. Aim for an a wake window about double whatever your last nap length was. So 30min nap means 1h awake time, and so on.

This sounds like my dd great sleeper 4m sleep regression which came at almost 5 months sent everyth8ng crazy! Could be 4 month regression it’s not always 4months but 3 to 6 month regression doesn’t have the same ring to it.
