Holding bottle

Are your babies holding their own bottles fully yet without any help at all? Or if you have other children what age did they start to hold their bottles? My daughter was around 2 months for a little until she got tired and then around 3.5 months she started holding it completely by herself but now she just doesn’t want to at all.😂 I know it’s okay and it takes time but it would be so much easier if she could hold the bottle especially at night when I’m super tired and can hardly stay awake to hold it.😬
