Oh, I feel for you, I really do! Just hang in there, B.. It will get better, trust me! What you are feeling is totally normal. I know I have been there plenty of times, especially when my DD was that age.
If he is fed and his diaper is clean, then there are a few things it might be.
- he might have some gas. Is he burping ok during and after eating? DD was really bad about burping and had reflux, so we had a heck of a time with that.
- Has he been pooping as usual?
- Is he peeing as usual?
- If he's on formula, have you changed it recently?
- If he's breast fed, did you eat or drink anything that you haven't consumed before while BF?
- He's young to be cutting teeth, but it's possible. If his gums are hard and you can feel any little bumps, that might be the issue.
If you need to step away from him, it's ok. Put him in his swing, crib, bouncy seat or whatever. As long as he's strapped in (if applicable), he will be fine. Take a shower, step outside to get some fresh air, just get away for a few minutes. Not suggesting you go to the store or anything w/o him, but take a break ;-) You deserve it, and it will do both of you a world of good! I wish I could help you better, but know that you are not alone!
