Mom's... I feel like a horrible parent... please help me, I feel like I'm in a funk!?

I have a 10 month old son who I absolutely love to pieces... I do not question my affection for him at all... however, I have been feeling lately as though I do not want to take care of him sometimes.... Not that I don't care about him, but that I've been feeeling very lazy lately.. I don't know what my problem is... I love my son to pieces but for the past few weeks I've been feeling so overwhelmed with taking care of him and I feel like I'm rebelling against myself if that makes sense.... I WANT to be a good mom and take care of my baby but at the same time I don't... I just want to sit back and relax and not do anything... For the past 3 weeks my husband has been waking up with our son in the mornings and getting him his bottle and breakfast and I stay in bed and sleep in... I used to be the one who got up in the mornings but Ij ust don't have any desire to do that anymore... What is wrong with me? I feel like I"m in a funk and I'm being a bad mom temporarily and I don't know when it will stop or how to stop it... I'm just so lazy and disgusted with myself... I want to be a better mom I ijust don't FEEL like it if that makes sense.
