My first thoughts were that you need to know her 'love language(s)'. A Christian psychologist has written a book about "The Five Love Languages" ( www.fivelovelanguages.com ) but this is the basic idea:
Every person is born with different needs and personalities, and we need to be dealt with accordingly.
The ways that make people 'feel loved' are:
1) Physical touch (any LOVING touch -- a pat, hug, kiss, holding hands, having your arm around them, etc.)
2) Words of affirmation (any positive statement about them -- a compliment, encouragement, 'thank you', etc.)
3) Quality time (just being together -- talking, walking, riding, cooking, shopping, watching TV or a movie, etc.)
4) Acts of service (doing things for them -- putting their things away or anything that 'does' something for them that they'd rather not have to do themselves).
5) Receiving gifts (whether large or small -- giving them actual tokens that prove that you were thinking of them).
Most people have one most important 'need' (Language), and one or two secondary needs. If you can realize which of these are your daughter's BIGGEST needs and try to do more of them, I think it'll help a lot! Her needs are probably quite different from yours -- ways of showing love that are NOT very important to you, so you would just never think of them as being important to someone else. Your older daughter probably has needs similar to your own, so there' never been a problem. I've lived with my husband for over 33 years, and I STILL don't know his love language(s) very well, and he doesn't know mine!! With kids, though, you can usually tell what they're missing because they TELL you what they want/need (or else they gripe about whatever's NOT being fulfilled). If you haven't noticed what she needs, talk to some of your relatives and/or neighbors who've been around her a lot and ask what they've noticed that makes her happiest.
If she's a 'quality time' person, she might even ENJOY following you around as Shellie suggested, and that would be great!
Just try it! It can't hurt anything! Good luck and God bless!
