Re: pressured to pump
with the excellent advice from the PPs.
I think you should have a quiet, just-the-two-of-you conversation with your husband and make it absolutely clear that one, you have no interest in making pumping and bottles a routine, everyday part of your life, and two, that sleep-overs with grandma are not likely in the near future. He needs to back you 100% on these two things, no arguments, especially when it comes to dealing with his mom. A son can say things to his mother that a daughter-in-law cannot!
Carm3 put it so well: feeding the baby is NOT "helping out". It's just more work for you. If your DH and MIL want to help, give them specific instructions for tasks that they can take on. Like doing laundry. Cooking meals. Mopping the floor. Scrubbing the toilets. Those things aren't nearly as much fun as cuddling the baby (which is why no-one is offering to do them, instead), but they are actually useful, and they free you to do what should be your primary concern at this point: taking care of your newborn!
