Don't give up, mama. I've been there myself and was often tempted to just stay home (although my church has a cry room with speakers, which is a great advantage, although DD is usually pestering me so it's hard to hear anyway). My DD is now a year old and has always been very high needs--first it was colic and now she is super-active. There were several times I left church in tears, so frustrated that I was missing so much of the worship service at a time in my life that I so desperately needed spiritual guidance and encouragement, dealing with her high needs and having experienced some PPD. I had a talk with my pastor about the situation and the fact that I felt like a horrible Christian since DD was born. He assured me that although I may not be able to give the same focused attention I had before, that God would still bless me for being there and taking part as much as possible, and that tending to DD actually is a form of worship itself since we are raising her in the church! What a comfort that was to me! Our church does not even believe in nurseries because we want to teach little ones to pay attention as soon as possible. So, when we get there, DH and I keep DD in the sanctuary as long as we can--she tends to behave a little better during singing--and then one of us takes her in the back when she becomes too rambunctious. Maybe you and your husband could take turns like this. Also, the baby monitor suggestion sounds like a great idea. Whatever you do, persevere--God wants you and your family in church despite the obstacles you face. It will get better! Remember that in whatever you are doing is an opportunity to glorify God, including chasing after your little one!
