My in laws got here today. It almost feels strange having help again, because my parents left a week ago. Rachel and I are starting to develop a rhythm, and I feel kind of bad that this means I hold her 99% of the time. They also don't recognize her "nursey face" too well but we'll work on that,
Don't feel bad! Lucy LIVED in the moby for the first few months. I think it irritated my in-laws, they thought I was going to "spoil" her. Whatever.
Totally understand the "nursey face" part, too. There were soooo many times Lucy would be hungry (to the point of crying), and my MIL would continue to try to soothe her, even after I said things like "I'm pretty sure she needs to nurse." She would just ignore me, like she thought she knew my baby better than me. It caused a lot of hurt and I shed some tears over it. Finally I got up the confidence to walk up to her, say "Lucy is hungry and needs to nurse," and literally take her.
I hope your ILs are more communicative than mine, but if they're not, don't be afraid to be confident and assertive in voicing your feelings. It'll actually make things easier down the road.
