i know how you feel. My DD is 23 months. I watch a 6 and a 9 month old and a 14 month old. I used to call up my husband crying that i didn't want to do this anymore. They all seemed to need a bottle at the same time or just need to be rocked or something. My DD and the 14 month old fight all the time. So i would be feeding a baby and would be pulling the two toddler apart. For a couple of days i didn't want to do it anymore either. BUT i had to realize that they will get older and start crawling and walking. the 9 month old is now crawling and the 6 month old is now occupied on the floor or bumpo. Months ago it was bad. Plus we couldn't go out so i was stuck inside all day for what.. 3-4 months.
Trust me, they will get older and things will get easier. The reason i wanted to start with infants is so they can all play and interact ALTOGETHER as they got older. And i could do circle time with on age group.
Hang in there, it'll get easier, trust me, i was there!
