I remember those early days so well and it really is hard
you could try a HAB or wrap style carrier that means bubs will be more upright which should help with reflux. DS was the same and it just felt like I could not put him down, I kept reminding myself that we were one for 9 mnths and so it is fairly reasonable to him that he would want to be cuddled and reassured in this strange world. TBH (and sorry if this grosses people out) there were weeks were I didn't have a shower everyday. Have one when DH is home and let him watch DD. Another tip Sleep when she does, the housework will wait but this time will go by soooo quickly.
