My 4.5 YEAR old still doesn't hold his own bottle...of course, we haven't given him once since he was about 18 MONTHS old, but I bet if we could convince him to use one, he'd still look at us like "well...?"
My husband and I used to laugh and say that he was actually VERY smart..."why if I start to hold that thing, they're going to expect me to ALWAYS hold that thing, no way." For some reason he wouldn't feed himself oatmeal either. Other stuff, absolutely, but he just wanted me to feed him his breakfast. It wasn't for lack of trying...he's my oldest, I'm sure I made mistakes.
And yet...I loved holding my children while they had their bottle...it was a nice bonding time...a quiet time when you can just spend a few moments looking at them and cooing over them. It's a special time. (My kids are adopted, so breast feeding wasn't an option for me...and I think you need to do what is right for your family and your body on that one...in a perfect world we all have things we would do differently...do you live in a perfect world? I don't! :-)
As far as feeding solids goes...in a few months you'll find yourself thinking "I wish he'd just let me feed him"...because you don't feel like cleaning up another mess...because you're in a hurry...because you want to be sure some of the food lands in his tummy...
With #2, she wanted to feed herself and I just had to give her the spoon and walk away. Not too far, of course, but far enough not to be right there...because the mess, which I found very endearing with #1, was another mess to clean with #2. LOL...on the other hand...at 19 months, she's gotten pretty darned good at feeding herself and there's not much mess most days. And I also knew the benefits of her feeding herself early would outweigh the mess in the long run.
One thing I find helpful is to give them a spoon to hold when you feed them...they start to wonder "what it is that I'm supposed to do with this thing?"...
He'll figure it out. I never met a 5 year old who didn't feed himself. Every kid has their "thing" that is unique to them...no other kid eats like/dresses like/bathes like...something like my kid! They all do things in THEIR time. The hard part is to let go of our expectation of when WE think they should do it.
I'm guessing you're an awesome mom...
