I don’t feel like my baby spends a lot of time awake

My daughter is 14 weeks old. We do tummy time a little a day but she doesn’t like it. (She spits up every single time) She has rolled from her back to her belly twice but she really has to work for it. She’s rolled from her belly to her back once but I think it was on accident lol. She still sleeps a lot (only on me of course 😅) she’s 14 lbs. she tries to talk to me some, she has good head control. I just feel like there aren’t enough hours in the day!! She eats 4 oz every 3.5 ish hours. I just am so scared we’re behind or we’ll get behind. She is starting to teeth so that could be why she’s sleeping a lot. She stays awake about an hour to an hour and a half after a bottle and wakes up about 30 minutes before a bottle. If we’re out and about she doesn’t sleep at all. Last night she slept 8.5 hours straight. (She sleeps with me. Don’t care what you have to say ab that. It’s not up for discussion) Does this sound normal??
