Meltdowns, how I love thee

Well DS just had a meltdown at the park.  Good god how I hate these.  I feel like every parent is looking at me when this is happening.  He's screaming and crying the whole way home and I'm just livid from him doing this.  He decided to have a fit cause he wanted to see his friend on the baseball field, well they were playing baseball and I told him no, to wait till they are done hitting the ball.  He throws himself down and does his best impression of a spoiled brat.  He then proceeds to BITE my leg.  Not hard but enough to know u are getting bitten.  I was shocked.  I first made him get up, brushed off the dust then started the walk of shame.  I don't like this walk.  I feel terrible that I can't make him stop, feel bad that he's feeling this way and obviously can't handle whatever it is that's upsetting him.  I also don't like this walk cause it seems like every parent within a 10 mile radius happened to be at the park at that time. I was so angry when we got home.  I sent him to his room.  Took out all his toys in his room.  He's not going to the park again till Sunday (might be Saturday, days tend to run differently to us adults and kids) and no TV at night before bed.  He did say sorry on the way home, but he was only saying it so he could stay and I need to teach him that he can't bite people without some consequence, right?  He then apologized at home after I sent him to his room for a bit.  I gave him a big hug, and thanked him for saying sorry but that what he did was wrong and he won't be going to the park for a while.  He just nodded his little head and my heart broke.  I started to bawl.  I felt awful for snapping at him earlier when we got home.  I told him I was sorry, for yelling, and my yelling didn't help much.  I feel terrible and don't feel like I'm a good Mom at times.  Sad thing is that if this is upsetting me now, how am I going to handle this when he gets older ? *sigh  Crappy thing is he had a good day today.  Had fun at a friends house for a play date, great afternoon playing the backyard, wasn't till we got to the park that he pulled this stunt.  Though ... he does do it every couple of weeks.  Can't expect him to be perfect all the time, cause God only knows I'm not. :)  Bad days can happen and I guess I should be more prepared for them cause baby #2 is on his way so it's going to get tougher.  Nice thing is, tomorrow is a new day, fresh start.

Best Wishes
