aw_bb, my boy is 2. travelling with toddlers are tiring cos of the barang to bring, then they are forever so energetic. and when they are tired, they ask u to carry. so for now, my hb says very bo hua for him cos he gotto do almost all the things like carrying, going into the water etc. but the smiles on him when he is so happy is priceless. so as parents, we will complain and rant but still go ahead and do.
hb - maybe u can try say when only 2 of u are having a good meal and not in any bad mood, talk abt the issue calmly and with some humour. when everyone is relax, things go into the head and less likely to break out in fights.
actually going away can make or break the r/s. some feel that separation for a while can help but some feels otherwise cos it really makes u think, maybe it's ok without him/her.
carters also having sale! and i'm looking at the so cute rompers. so much of having the same gender for no2. lol
