Hey there, new mama with stars in your eyes, cradling that precious newness and measuring yourself suddenly unworthy of the blessing she is and the trust she unreservedly gives.
Just breathe. You are enough.
You will fail at your most cherished ideals, and you will misunderstand her. You will follow ideas that seem sound and then learn to adapt all over again when those foundations slip. Even your worst days won't break you. The curses spoken over you as a teenage mother will come to nothing, and you will prove those judgements wrong, because they are speaking out of fear and their fear has no power over you. There is nothing you can't learn from, and it will be OK!
Remember to say sorry, allow your heart to be tender and soft, work to forgive and act in ways that are grace-full and gracious - she will try to become what you are. Permit yourself that same grace when you mis-step. Because you will, and it will spur you to choose and choose again, more love, more peace, more joy.
Take brave baby steps and try things out. It's perfectly healthy to try a little and see. You can decide that something isn't for you. You can take a step in a different direction. You don't need to have a grand theory or figure everything out in advance. See the big picture and don't sweat the small stuff. Most of it is small stuff!
It isn't all yours to control.
You don't need to do it all. Your baby doesn't need a "perfect parent", she just needs you. Look, truly look, at your child, how she really is. Try to observe her without filters. She is a whole person already. You are forming a relationship with her, not with the child you thought you'd have, not with a mirror or a part of yourself.
Hold her, treasure her, don't worry about putting her down, babies don't spoil. You won't disappear or be swallowed up in giving yourself freely to her. Trust that immense love, that overwhelming bond with her, there is no such thing as too much love. Listen to even the most bizarre advice openly, and think on it, but run from blindly following *anything* you are told no matter how trustworthy the source. They are not you, and they can't know your baby in the same way you do.
When she cries, and she will, it is not about you and it is not personal. She is communicating something, yes, and you can help her, yes. But sometimes the only way you can help her is to be there - and sometimes she will still cry. She doesn't hate you. Look for the need, but let the pain flow away from you - it isn't your pain to take in. You can listen better if you are not frantic with the pain yourself.
She is not you, and you are not her.
Give her chance to relate to other people, in their own way. It's not a big deal that daddy changes her nappy differently, plays with her differently, gets the words to rhymes wrong. They will find their relationship more comfortable and much happier if you don't try to take over. A lot of the fears you have about things that might damage this precious baby are honestly just versions of the fear that you are no longer in control - well, not to be rude, but get used to it! - don't put that fear on to other people.
Appreciate the small things. You already have much more than you think you do. To slow down this crazy race, simply look around you and be in this moment, here, now. Time is not getting away from you, and it is never lost, all of this time is a part of you and will be forever. The layers are beautiful. And she will *always* be your baby.
Make space for yourself too, and fill your own cup. Find those soul sisters you can tell anything to, and treasure them. A tribe will shore you up when you need it, and celebrate you when you are dancing along in tune with each other.
Surround yourself with people who speak both love AND truth, but especially with people who see the positive, can laugh at themselves and disaster both, and encourage you to go on seeking the positive, the admirable, the worthy.
Laugh with her. Say yes as often as you possibly can. Have fun together. Be her safe place. Ask what she thinks. (And for in a couple of years, you need to know this: Stop bloody correcting her. Believe me, your inner teacher will come out when she starts talking, and I'm telling you it won't help. Trust her to ask if she needs to know. She'll forgive you, though, and you will figure out how to talk without constant "lessons" coming out of your mouth.) Learn to play, run barefoot in the grass, so many beautiful things are opening to you as she opens to the world. Embrace wonder!
This is only the beginning. I know you don't feel like you're doing that well, right now, but the things that you are growing in to will change everything. Trust yourself to figure this out, one small step at a time. You are already a wonderful mother, and just the mother this child needs. Or at least, you are growing in the right direction.
