So harsh to this nanny, PPs (and I am a Mb!). Look, you can't tell mom how to raise the baby. And no, you won't spoil the baby at that age. It sounds like you have a way in mind, but you do have to accept that Mbs way isn't necessarily wrong or faulty based on the child's age and stage. But if you want it to work with Mb long term, you do need to be on the same page (and I'm pretty sure it needs to be mom's page, not yours) and you may as well use this time to start working it out together. How about sitting down with mama and asking her how to handle the issues you see - something like "I've noticed every Monday that baby has trouble with getting back to solids/bottle and I'm wondering how you'd like me to handle it? Right now we power through it, but I want to work with you to transition her better after the weekends." Or "I see that baby wants to be held constantly right now, and while I am happy to snuggle her all day, I want to make sure we use the same soothing tactics and give her some independent time. Should I always pick her up when she cries just to be held, or should I try to engage her with toys/tummy time to help her start to self soothe and self entertain?" Maybe mama says "no, always hold her" but if so you have your answer. Or maybe she too is exhausted from holding her all the time, but feels like she has to, and would like an ally in helping baby begin tiny steps toward being able to sit in a swing or bouncy chair for a few minutes at a time. Important thing is to have a conversation about what you two can do together, not one that begins with the premise that one way or the other is the only correct way.
