hi
I do a joint bath every evening after tea as well. And have done since Emma's belly button healed around 4 weks old. Before this, I sponge bathed her during the day....at four weeks till around 2 mths, Emma was bathed in our batrhoom sink which is a bowl type shape and worked really well for me, while Oscar was in the bath alone, next to us.
If Dh is home, he gets in the bath with both of them.
IF alone, since Emma turned around 2 mths then I fill the bath up to a puddle only first, get her in washed and out and then as I am massaging her, get Oscar in to have some fun quickly.
If short on time, I will lay her down on the bathmat and shower her quickly and then give him a shower standing up.
Emma gets really sore in her little cracks between her chubby parts (even backs of knees and definately between all her chins LOL) if she is not bathed, oiled and sudo-creamed daily! And as for Oscar, well, he's just too filthy at the end of the day!!!
Can't wait till she can have a "proper" bath with him! Sat her in the bath today, propped on my arm while Oscar was already in.....she was amazed that she could sit there with him...and he was ever so gentle as usual!
But, yes, bathtime for us is total wind-down....for all of us....a proper end to a long day!
