genia,
I felt a bit like you in the first few months after dd was born, I was doing all the feeding nappy changing bathing, while dh and mil would snatch her from me that moment all the above was done to let me rest/do the shopping/cooking etc... as if I cared!!!!!
I always try to make time to have fun with dd, maybe during a nappy change (just saying silly things to her) or a bath. I don't have the patience dh or my mother have to do endlessely repetitive games, simply because I'm always aware of all the other things that need to be done, while they're only there to entertain dd. But I also make sure dh shares in the boring tasks, like feeding, changing, dressing up whenever possible, so she understands we are interchangeable.
She might prefer dh or other relatives to play with, but when she's tired, sick, or simply wants a cuddle she tends to look for mum.
Which is nice, but can be tedious as well, when she's ill and wakes up every half hour at night, I don't want to be teh only one to go to her!!! (she's now happy with either of us going to reassure her)
Genia
I wouldn't worry too much, it's also an age thing, my dd went through a daddy phase too, but at one point she was so clingy to me that I felt like a mother koala with her on my hip all the time.....It's always healhty that a baby forms attachments with other adults too (for the baby and IMO for the mother too), but I'm no one replaces mum whern they're in need of a cuddle!!!!
