I am feeling the baby a lot at the bottom. I am 20 weeks along now which is shocking. This pregnancy has flown by.
Purple I totally hear you. BF was impossible for me with DD as my milk didn't come in and with DS he was 10lb6oz so was losing weight rapidly before my milk came in. He was having problems with regulating his blood sugar levels and the specialist advised that we FF and pump. I HATED pumping so decided to FF. I think a happy mother is far more important than sticking with BF when it just isn't working for you.
What I have learned from having my first two is that people will always give you their opinion regardless of you asking for it or not. Best approach is to smile and nod. In your case I would have said to your OH's mum - that is great that you are so willing to support me trying to BF. I am nervous because I hear it is quite painful at first and the frequent feedings leave me worried that Dad is going to be left out. This gives her a role to help you BF - doing the cooking and cleaning! Also, she has done it before and values it. If (when, in my case) your OH complains to his mum that you spend all your time with the baby she will be highly likely to support you.
I will try to BF with this one again with the goal of making it to two weeks and if it doesn't work then we will move to formula. I saw it that my first two got the advantage of the first 3 days of BF which is more than what others get. My experience was that it was bloody painful and exhausting to BF so I am trying to set myself up for success. Get yourself the proper support if you want to make a go of it. I have already asked around for lactation consultants who do home visits but you also need to have help at home for the first couple of weeks otherwise the house looks likes a shit tip and you find yourself ready to eat spam out of the can because you are so damn hungry but don't have the time or energy to cook a proper meal. I am in the US and our health insurance covers 100% of the cost of a pump and in-network BF consultants. They also cover 50% of the cost of a night nurse during the first 2 months. I am damn tempted to take full advantage but I will be having a night nurse during the first two weeks home.
The hospital gave me nipple shields with DD and I used them for DS. Those things are absolutely awesome and I always suggest every mother BF for the first time uses them from the get go. Also, the creams are essential. I was given the lavenosh cream which is good but after DS was born my friend gave me motherlove nipple cream. I found that the motherlove cream worked better for me. Get both!
Overall though, when my mother got all huffy and puffy with me for not BF I realized it was her issue and not mine. I keep reminding her that she has had her turn at mothering babies and now its my turn to mother my baby. I do not suggest you say that to your MIL but I do suggest you tell your OH to say that to his mother if she becomes overbearing.
