Dear Mama.
How to say it?
I have no clue.
But here's a little something for you...
Spring is coming.
Busy, busy.
New is everywhere.
Far too much to do.
Sunday today.
Sleeping in.
At church 'till lunch.
Garden all evening.
Morning Time.
Gotta get moving.
Still to sluggish.
Just wanna watch TV.
It's Monday now.
Hungry, hungry, need food now.
Go to work, walking all day.
Bed time, so soon.
Summer's here.
Almost calm.
Still to busy.
Swim it off.
Too soon it's Tuesday.
Empty morning.
Leaving home again.
Run round town all day.
Already noon.
Haven't gotten anything done.
Clean, need to clean.
Days should be longer.
Wednesday, weeks half gone!
Leave the house early.
Gone all day.
Get home tiered.
Time passed so fast, here's autumn.
Pretty colors. Falling leaves.
Life's finally calm.
Just for now. Just for now.
Thursday, uh, Thursday.
Need to work this morning.
Noon, leaving for band.
Staying out 'till late in the evening.
Finally night!
Sleep tight.
This wont last long.
Gotta get moving again soon.
Friday, Friday.
Working twelve hours.
Always on your feet.
Need new shoes?
Winter already.
Snow, snow.
Things start to pick up.
Already, to much stuff to do.
Saturday. Oh dear Saturday!
Finally the house gets cleaned!
A little bit of rest.
And now we're ready for Sunday.
Dear Mama
All for me.
Week after week.
Thank you.
I was wondering what this poem tries to convey exactly. Maybe how you mom is there for you through your weeks? But it's a cute poem. I like how you have used few words on the lines and has still managed to create so many images. I don't think I need to point out the spelling mistakes as someone else already did, but you really must understand the difference between 'to' and 'too'
that's one mistake a lot of people do and it's quite childish to be honest with you. All in all, quite an effort 
Thank you.

I see how the point could be confusing to you. I'll think about that when revising this. But it's not that high on my list of things that need attention, because I'm fairly certain that my mother will get it.
Thanks again.
"Still to sluggish." - too*
"Still to busy." - too*
"Get home tiered." - tired*
"Already, to much stuff to do." - too* (too much stuff to do)
"Wednesday, weeks half gone!" Depending on how you wanted this to read, it could be weeks, as in multiple weeks, are half gone, or week's - 'week is' so that is really up to you.
So aside from these minor punctuation things, I'd like to take a chance to explain something I think you might be misinterpreting. You said at the beginning that you get nailed for rhyming when you're not focusing on rhyming, and then you get nailed for using forced rhymes. I think the problem is that you rhyme sometimes, but the poem is not a poem that focuses on rhyming, so we get a contradiction going on. Sometimes you rhyme, sometimes you don't. For several readers, that can be very frustrating. For instance, when you repeat words at the end of lines, you end up actually creating a rhyme, or things like 'Tuseday' and 'all day' there is a rhyme there, but the rest of the poem is absent of them.
For the general content, I'm not quite sure what message you're trying to send your mother? This poem seems like it's just a list of everything your mother does for you. I'd really like you to try taking what your mother means to you, what all of her work she does for you actually makes you feel, and write that out as plainly as you can. If you're mother's a poet, go ahead and write it poetically, but I think the more honest, and the more exposed you make your emotions, your opinions, and, in the end, your heart, the more it is going to make your mother cry. Try taking this poem and take each thing she does for you, and attach what it means to you. For instance: 'Finally the house gets cleaned!/Refreshed from your soft hands/brushing away the dirt on my head/and no more stress about that horrible stain in my heart' or something sentimental like that. Think of ways to express the personal. This poem seems impersonal from my perspective, but I don't know your mom, or your relationship to her, so I might be completely off base in that assessment.
Thank you. What you've said here will be very useful. But I feel like you never made your point about me sometimes rhyming. I understand what you're saying, but it feels like there was something else to it. That might just be me though.
This is adorable!
Fourth stanza:
Did you mean to capitalize time?
"Still 'too' sluggish"
Sixth stanza:
"Still 'too' busy"
Stanza nine:
"Wednesday, 'week's' half gone."
"Get home 'tired.'"
I think you've broken it up too much with all the periods. Try mostly commas at the end of lines unless it's the end of a stanza.
My favorite line: "At church 'till lunch."
I love internal rhyme scheme.
Thank you for the suggestions!
Hope I helped!
