I feel like a bad mom

Hi,

So I am almost 3 weeks postpartum with my 3rd child and I'm at a loss of what to do. My newborn has not stopped cluster feeding essentially since we've been home from the hospital. He is nursing like every hour on the hour for up to 30-45ish minutes. I don't sleep well at night because of this as well. I'm on maternity leave and been keeping my 2.5 year old and 14 month old with me when normally they'd be at the babysitter's cause I'd normally be at work. The thing is with new baby nursing all the time I can't seem to do anything with my other kids. I feel really trapped at home and would really like to be able to take them out to do stuff but I can't seem to even get off the couch due to baby eating. I honestly don't even know what to do with them by myself cause packing up 3 young kids is a nightmare all by itself. I feel like such a bad mom because all we do all day is watch movies and play with our indoor toys. They're used to playing with other kids at the sitters and spending time outside but we haven't been able to do much. I know it's partially baby blues but I cry about it constantly because I just wanna be the mom I was before baby number 3 arrived.
