Sounds to me like you have a certified velcro baby! I have one of those, although she is not as bad as she was. I found tummy time helped a whole lot. She is a lot better now because she wants to explore and look around and play with things she shouldnt, but still refuses to be unable to get to me, even if she doesnt actually want me. We have a baby gate across the kitchen and all hell breaks loose if I am on the other side of it to her. Give her some opportunities to be on her tummy but with mum in sight.

Also to get her more used to spending time with daddy we would have squishy 3 people cuddles with her in both our arms. Or sit her on the lounge between us so there is contact with us both. Velcro bubs can be wonderful for your self esteem, but can take time to cut the invisible umbilical cord they are holding onto. Be patient with her and take it slow so she still feels safe even though she is not on your lap. All she wants is to feel safe with her mummy.
