Hiya
(((hugs))) does this just happen during the day or does it happen during the night too? Is she taking a longer stretch of sleep on you? Is she sleeping at all during the day?
If I can explain it from her perspective, she falls asleep all warm & snuggly in your arms, then when she wakes up she is in her cot/moses basket & not where she was when she fell asleep. This will of course confuse & upset her, and if she has grown used to being cuddled or rocked to sleep, she will need you to help her every time she wakes.
I do understand how difficult it is though having been in the same position with my LO up until he was about 3 months old. Personally I quite like the snuggles when they are tiny, & esp if they are a bit unsettled it can really help to get you through those first few weeks but of course there comes a point when you want to try & help them learn to settle to sleep independently.
Firstly I would say that if anyone suggests CC or CIO it is not an appropriate sleep training technique for a baby under 6 months & is likely to make her very distressed. But there are more gentle techniques you can use if you wish to tackle this now.
We used the Baby Whisperer's ssh/pat technique to help our ds learn to go sleep on his own. In a nutshell you pat their back/bum while ssshing past (not into) their ear. This should help to calm baby down & then you gently lay baby down before they are asleep, while continuing to pat & sssh. And you carry on until baby is asleep. We did a modified version of this b/c ds slept on his back so we would place a hand on his chest or stroke his forehead & sssh. And repeat the same thing every single time you put baby down for a nap.
She will cry. There is no escaping that b.c you are teaching her a new way to go to sleep. If you you can persevere & be consistent she will quickly learn how to self settle.
Over time you can gradually reduce the assistance she will go to sleep on ehr own. It did take a few weeks for my DS to get the hang of the new way, but I am so glad we did it b/c since then, all I have had to do is put him down in his cot & leave the room & he goes to sleep on his own.
A couple of other things to note are also that at that age babies have strong reflexes & can often jolt themselves awake after a short time so BW have techniques to help with this too. Also you might want to keep a record of how much daytime & nighttime sleep she is getting over the next few days & post that b/c if she is overtired this can also lead to her struggling to settle & waking after a short nap.
