Sleep advice 😫

My baby is 15 weeks and I usually rock her to sleep then lay her down in her bassinet no problem. Lately, the only way she wants to nap is in my arms 😫 I don’t mind the cuddles but I’m worried she will get used to it and it’ll be a hard habit to break later on. Now she will be wide awake once I put her down in the bassinet please let me know any advice or what worked for you mommas if your baby did the same thing 😅
