Oh I am having a hard time too. I did do one thing that helped me a LOT. I hired a 13 yr old "mom's helper" or baby sitter, whatever you want to call it. She helped me most of the summer. Even if for 2-3 hrs, makes a HUGE difference in your sanity level. She came over and played with my son while I focused on nursing (we had a small issue there) or even dosed off. She was FAB, took him tot he park, library and just played with him. Her energy level matches his so it was amazing for me. Now that he is in half day school (he's 2.75 too - 3 in Nov) it is easier. We did lots with the babysitter though, went to the zoo, on big trips. It was easy to sit and nurse while the babysitter chased my son and kept him out of trouble.
On the stroller, i hear you. We had a bugaboo (yes, it was a gift
) and I tried the wheel board but NO WAY my DS would stay on it, he jumped off and wandered off. I tried him in the stroller and my daughter in the mai tie (which she loved) but he HATED the single stroller. He'd fight and there was NO WAY I could ever let him walk our city sidewalks without fearing for his life, this kid WILL run into oncoming traffic and we live right in the city. Anyway, I tried a double stroller - told him he can sit beside his sister (its a side by side) and really did not give him an options. Well, he stays in it. He does ask to get out sometimes and I tell him, yes, when we get to X you can (home or school or park). He actually listens. He loves sitting beside her. This double is one a newborn can go in, she seems fine in it, mostly sleeps. Thank GOD b/c she usually needs to be worn all day. I got he Valco Trimode runabout 2009 model, it has separate sunshades, recline levels etc. I would highly recommend getting sep. sunshades b/c this was an issue when I tried a previous double with only one. DS wants it back, DD screamed everytime sun was in her face. Problem solved with two individual sunshades.
Anyway, this transition IS hard. Another thing that really is working for me, I think another mom mentioned it...hang out with other moms of two. The older kids can play and give you both a break to focus on your younger ones. I feel at least my DS is not bored or watching umpteen amounts of TV while I figure out nursing or just get a small break.....
I just want you to know you are not alone. I'm sure one day soon this will get easier! One day they will be playing happily together
