Sorry I forgot about your section; of course you can't feed lying down.
Wind at this stage in a bf baby usually indicates an oversupply and/or fast letdown. Poor O used to get sprayed by a jet of milk at the start of a feed. Stick with the infacol if it works for you.
A has slept on me since she was born. If I put her in the crib she'd flap her arms and look as if she was falling and scream her head off. I think the path of least resistance at this stage is just to go with cosleeping if that's what they want. I put the duvet up to my chest, A on top of it and then I've got a blanket which covers both of us. I prop up the arm hold her head up with a pillow so I'm not pulling out of my shoulder. Last night was the first night she slept in the crib for part of the night and it was great to be able to sleep on my side for a while. All the sleeping on my back is aggravating my sciatica.
I did a combination of crib/cot and co sleeping with O and I'll do the same this time.

she is just unsettled and unhappy anywhere else! Some nights she does a few hrs in the Moses basket but when she's very windy the only place she'll settle is on my arm! I'm so tired I just want sleep!!! Ill take it anyway it comes!
