My husband left to go work out of town when our daughter was 4mos, so I know how you feel, trying to do everything yourself. We couldn't use the carriers. I tried the sling one, she screamed the minute I put her in it; never stopped. She never liked not being able to see out of it. And the other one, that she sits up in strapped in front of you, well, that one worked OK, but she would only stay in that for about 20mins, and it killed my back as she got bigger. I've had severe back problems since pregnancy, so carrying her around all the time as she gets bigger (18 lbs at 8mos) just isn't an option. We had to buy several things and rotate her between them. I used a bouncer, a jumperoo (we got the one that's on it's own stand, but it takes up a lot of room), an exersaucer, the playpen, one of those gyms where I could lay her on the floor (had to put dog and cat up in the bedroom for that one), and even her crib, which has an aquarium and that panda mobile from fisher price (she loves that thing). And I would talk and sing to her while I did my work. Walks are good; I'd take my cell phone and make any calls I needed to make while I walked her in her stroller. She's eight months now, and I still have to do the same things. Except now she's got a few more things, like a walker and a play area where she has all her toys and she can spend some tummy time and practice crawling, and a little bike/stroller thing that I use to walk her around the pool when she gets tired of being inside. Sometimes she just plain gets tired of doing all the same things, so that's when I put her in the car and take her out to run errands - she likes getting out and seeing people and for some reason, she really likes leaning back and looking at all the signs on the ceilings at stores :) Do you leave him in the car seat, or is he sitting up in the cart yet? I started sitting Katie up at about that age, with a Floppy seat which protected her from the dirty carts and has places to hook lots of toys to keep her busy. I put my purse on one side of her, and usually kept my arm on the other until she got better at sitting up by herself. I forgot to mention - be careful with carrying him on your hip while you do housework. I did that with Katie one day while I was mopping when she was about 6mos old, and she kicked back in my arms so fast, she ended up hanging upside down by her leg. And we have ceramic tile floors. My heart just stopped. Thank God I had a good grip on her thigh when she did it. So, I don't carry her unless I can use both hands anymore.
