Is Pooping In The Tub A Milestone?

One more week and Shaun will be 4 months old. Everything has been happening so fast! I can't believe the year is almost over!

So a couple nights ago, Tuesday, I'm putting Shaun in the tub and he pees. Okay, that's normal. But then he's stil grunting and sure enough, a soft yellow turd floats to the top of the water. I'm laughing as I'm getting Shaun out of the water to put a diaper on him so I can wash the tub. I had to call Lisa too so I could share my woes! As I'm on the phone with Lisa, Shaun pukes down the front of my shirt and it drips into my bra - YUCK YUCK! So I change my shirt, clean the tub, fill it back up, take Shaun's diaper off (sure enough it's empty) and put him back in the water. And wouldn't you know it, he pooped again, this time more! Even though he was in the water it squirted all up his back and because he was moving around the floaters got all smooshed between his fingers and in his armpits. It was so gross. I'm sure all the neighbours know he pooped in the tub because I was shrieking and laughing so loudly. By the time I had scrubbed the tub again and washed and dried Shaun, the whole ordeal had been almost an hour. I had to call Lisa again after the second time and I called Mum and told her too... what a milestone!

As far as Shaun's schedule goes, I had tried last weekend to move Shaun into a 3 1/2 hour routine instead of 3 hours and he wanted nothing to do with it. I'm sort of puzzled now as to how I'm going to drop the 6th feeding and 4th nap. I think it will take some experimenting. Currently, this is what his schedule is:

Feedings/Naps

8:00 AM / 9:15 - 11:00
11:00 AM/ 12:30 - 2:00
2:00 PM / 3:30 - 5:00
5:00 PM / 6:30 - 8:00
8:00 PM / night time sleep from 9:30 PM to 8:00 AM
9:30 PM

Now the timing of the last feeding varies by about 45 minutes, depending on if I have the car or not. No car, the feeding is at 9:30, car, the feeding is at 10:15.
Eventually Shaun's last feeding will be at 8:00 and then he'll go down for the night. My thoughts are that for the next 6 days I gradually work back the last feeding to 8:00PM. Can Shaun do it in only 6 days?

Obviously there's the potential that the transition won't go so smoothly but we'll see. Shaun's pretty adaptable and he may surprise us! It's worth a try anyway.
