hen,
I tried bayb sling and Pikkolo carrier. I used sling on my #1 and feel not much pressure on my neck/shoulder due to him not a chubby bb. I rmb using the sling till 8th mth old then put him in stroller when outing. Now my sumo, I can't even use the sling when he was like 2nd mths... he is big, made my shoulder aches. So decided to change to carrier. I am very glad I made that decision, the carrier really give my arms a break, helper likes to use it too. Think now he already 9kg+, how to carry?!? He loves sleeping inside the carrier too.
I don't dare to let my helper used the sling cos worried that bb will drop onto the ground. I saw some helpers didn't use it properly, the ring's position in front of her chest in fact should be just after the shoulder. Pa4 Pa4
Pikkolo is pretty easy, imagine my helper(Indo) mastered it very fast too. This is how I do it.
Buckle up the waist strap first, adjust.
Loosen the 2 shoulder straps
Carry bb
Split his thighs
Bring up the carrier while bb is sitting into the carrier(bottom now supported by the waist strap already)
Support bb's back
Bring 1 side of the shoulder strap and buckle
Bring another side of shoulder strap and buckle
Pull each shoulder strap at a time and pull to
tighten
Looks troublesome but its easy!
